FAQ (Selected)
Q: Does flame-retardant silicone rubber produce toxic gases when it burns?
A: Our flame-retardant silicone rubber uses a low-smoke, halogen-free formula, ensuring excellent performance and environmental safety without toxic gas emissions.
Q: How to deal with cracks in the seal after long-term use?
A: This is caused by aging. We recommend upgrading to a higher-grade anti-aging formula product based on your application needs.
Q: What if the silicone rubber shock-absorbing pad cannot rebound after compression?
A: Our products have excellent elasticity and pressure deformation resistance. For higher requirements, we can customize the formula or process to improve rebound performance.
