Core advantages: strong performance adaptability
1. High efficiency of buffering energy absorption
The silicone foam board realises "deformation absorption - rapid rebound" through a three-dimensional mesh structure. The impact absorption can reach 30%-60% (adjusted according to density), far exceeding that of ordinary sponge (20%-35%). It can effectively alleviate the impact force caused by falling and collision. It is suitable for electronic equipment, precision instruments and other anti-impact fields. Scenery.
2. Outstanding weather resistance and stability
It can withstand a wide range of temperatures (-40℃~200℃), does not crack at low temperatures, does not soften at high temperatures, and has excellent anti-ageing and ultraviolet resistance. The service life of outdoor use (such as outdoor equipment buffering) can reach 5-8 years, far exceeding that of EVA foam (2-3 years).
3. Strong chemical compatibility
It has good tolerance to corrosive substances such as grease, acid and alkali, solvent, non-swelling and non-degradation. It can be used in cushioning scenarios such as mechanical parts and automobile engine compartments in contact with oil and chemicals, while ordinary polyurethane foam is prone to corrosion and failure.
Product features: flexible scenario design
1. High degree of customisation
The density (20D-80D), thickness (1mm-50mm) and shape can be adjusted on demand, and the die-cut can be cut into shapes (such as round, wavy), perforated (ventilated holes, weight-reducing holes) or composite (fitting with fabric and plastic), and adapt to the installation space and cushioning needs of different equipment.
2. Excellent environmental protection and safety
It uses medical-grade/food-grade silicone raw materials, formaldehyde-free and odourless. It has passed RoHS and REACH certification and does not release toxic gases during combustion. It can be used for children's products, medical devices (such as wheelchair cushion cushioning) and other scenarios with high environmental protection requirements.
3. Multi-functional integration
It has multiple functions of cushioning, sealing, heat insulation and anti-slip. For example, electronic equipment foot mats can realise shockproof buffering and anti-slip fixing at the same time; home appliance sealing strips can take into account buffering noise reduction and dustproof sealing to reduce the cost of multi-part matching.
4. Easy to process and install
The texture is soft and tough, and it can be directly cut and pasted (the back can be covered with glue). No complicated tools are required. The installation efficiency is more than 30% higher than that of metal buffers, and the weight is light (density 0.2-0.6g/cm³), which will not increase the overall load of the equipment.

FAQ:
1. The buffering effect is not as expected. How to solve it?
• Reason: The density of the foam board is too low (<25D), the thickness is insufficient, or the adaptor structure is not selected according to the force scenario.
• Answer: Choose a high-density model according to the load-bearing needs (choose 30-40D for a load-bearing capacity of 5-10kg, choose 45D+ for more than 10kg); increase the thickness (it is recommended that the cushioning thickness is not less than 8mm), or adopt a "multi-layer superimposed" design; choose foam with "wavy" and "honey" structure for impact scenes. The buffering efficiency of the board is more than 30% higher than that of the board.
2. There is a permanent depression after long-term pressure, which cannot be rebounded. What should I do?
• Reason: Exceeding the rated load of the product, the continuous pressure time is too long, or the return performance of the raw material is poor (poor quality silicone contains recycled materials).
• Answer: Replace products that meet the "fatigue test standard" (need to pass 100,000 compression rebound tests, rebound rate ≥85%); avoid single-point long-term heavy pressure when using, and regularly flip the foam board to disperse the force; slight depressions can be dried by warm air around 60℃ for 10 minutes to help restore elasticity.
3. It does not fit tightly with the protected object and is easy to shift. How to fix it?
• Reason: The surface of the foam board is smooth, the size does not match the object, or the fixed design is lacking.
• Answer: Choose a style with a "self-adhesive adhesive layer" (such as 3M back glue) on the back, and ensure that the surface of the object is dry and clean before pasting; shaped objects can be customised to cut foam boards (cut flatter with an electric knife); assist in fixing by ties, Velcro or packaging tape, avoiding direct use of strong glue (which may corrode the foam board) .
4. How to deal with water absorption and mould after contact with liquid?
• Reason: Although ordinary silicone foam board is waterproof, it is easy to retain moisture at the joints or cutting surface; in a humid environment, the surface is easy to breed mould.
• Answer: Choose a "fully sealed film" or "waterproof coating" foam board; absorb moisture with a dry cloth immediately after moisture, ventilate and dry; wipe the mouldy place with diluted white vinegar (avoid bleach, which will damage the silicone structure); in wet scenes, give priority to the "mould-proof type" with antibacterial agent.
5. After cutting, the edges are rough and slag falls off, which affects the use. How to deal with it?
• Reason: The cutting tools are not sharp (such as ordinary scissors), or the high-density foam board is hard in texture, and it is easy to produce debris when cutting.
• Answer: Cut with a sharp art knife, electric heating knife or laser cutting machine, and keep the blade perpendicular to the board surface when cutting; the rough edges can be gently polished and smoothed with fine sandpaper (more than 400 mesh), or apply a small amount of silicone edge sealing glue (choose a model compatible with the foam board).
6. Is it normal to soften and deform in a high-temperature environment?
• Reason: The maximum temperature resistance of ordinary silicone foam board is about 120℃, and it will soften if it exceeds the temperature; the temperature resistance of inferior products is worse (<80℃).
• Answer: For high-temperature scenarios (such as heat dissipation buffering of electronic equipment), it is necessary to choose a "high-temperature-resistant model" (temperature-resistant 150-200℃, adding high-temperature-resistant siloxane component); avoid direct contact with the foam plate to the heat source (such as radiator, heating element), and can be used with heat-insulating plate; if the cooling cannot be restored after softening deformation, it needs to be updated Change to products that are suitable for temperature-resistant levels.
7. The product has a pungent odour. Is it harmful?
• Reason: The new board may have trace amounts of volatile organic compounds (VOC); poor-quality products use recycled materials or unqualified additives, and the smell is long-lasting and harmful.
• Answer: High-quality products can be eliminated by ventilation and drying for 1-3 days, and comply with GB/T 27630-2011 "Guidelines for Air Quality Evaluation in Passenger Cars"; if the smell is pungent, lasts for more than 1 week, or harmful substances such as formaldehyde and benzene are detected, they need to be discontinued and replaced immediately; "no" is preferred when purchasing Odour" "food-grade/medical-grade silicone" certified products.
8. When used for buffering electronic devices, how to avoid worrying about conductive or scratching components?
• Reason: Ordinary silicone foam boards may have static electricity, and the rough edges are easy to scratch the precision components.
• Answer: Choose "anti-static model" (surface resistance 106-10¹¹Ω, add carbon black or metal fibre anti-static component); polish the edge after cutting, or choose the pre-formed "shaped cushion" (factory prefabricated, smooth edge); contact surface with the component with "fluff" or "PE film" coating to reduce scraping Risk of injury.
9. How to choose different buffer scenarios (such as packaging, electronics, machinery)?
• Reason: Different scenarios have different requirements for cushioning, temperature resistance and strength (for example, packaging needs to be lightweight, and machinery needs to be wear-resistant).
• Answer: 1 Packaging buffer: choose low-density (25-30D), lightweight, low cost and easy to cut; 2 Electronic buffer: choose anti-static, high-temperature resistant (120℃+), thin (3-5mm); 3 Mechanical cushion: choose high-density (40D+), resistant For grinding and oil-resistant models, the composite foam board with "fabric reinforcement layer" is preferred.
10. How long is the service life and when should it be replaced?
• Reason: The service life is generally 2-5 years, affected by the frequency of use, environment and load-bearing.
• Answer: The following situations need to be replaced: 1 The permanent depression depth exceeds 1/3 of the thickness and cannot be restored; 2 The surface cracks, slag falls off, or the elasticity drops to less than 60% of the original state; 3 The failure of temperature resistance, anti-static and other functions (such as frequent electrostatic damage to electronic devices); 4 Mould and odour appear Problems that cannot be eliminated.
