High temperature fire-resistant insulating tape LS-985
High-temperature fire-resistant insulating tape is a new type of composite material. The residue after combustion does not melt or drip, which ensures that wires, cables and accessories are not damaged in case of fire, and plays a solid protective role in the smooth flow of electricity and communication.
Liquid silicone rubber for leather
Leather liquid silicone rubber is a silicone rubber material specially designed and developed for leather processing and related applications. It exists in liquid form, has excellent fluidity, and can easily perform various processing operations. This silicone rubber is carefully formulated with high-quality silicone polymers, cross-linking agents and other special additives. After curing, it can bring unique performance improvements to leather products.
HTPVSi is a kind of silicone rubber thermoplastic elastomer which is easy to process and shape. Compared with ordinary thermoplastic elastomer, HTPVSi has more excellent coating and unique human aesthetic touch, and has excellent mechanical properties, wear resistance, high and low temperature resistance. Performance characteristics: good mechanical properties, wear resistance, high and low temperature resistance, processability and silky touch, recyclable, green environmental protection. Excellent adhesion to polar substrates such as PC, ABS, nylon or non-polar substrates such as PE and PP.
