How about the insulation performance of PET Velcro Braided Sleeve?

Silicone is the trade name for many products, but most are made from polydimethylsiloxane (PDMS). These polymers are characterized by high covalent bond strength and resistance to chain scission (silicones are ultraviolet (UV) stable, thermally and chemically stable and easy to sterilize). Its polar main chain is prone to chain scission, but the methyl group on the chain can provide protection.

Therefore, silicone is hydrophobic, and the contact angle of water on the surface of polydimethylsiloxane (PDMS model) is higher, which is 108°. Due to this hydrophobicity, in the case of insufficient surfactant, silicone and aqueous media There is no reaction, only in the environment of strong alkali and strong acid.
Cable Sleeve is supplied extruded and packaged, typically in coils totaling 50 feet, individually mounted in double-sealed polyethylene bags. It is worth noting that silicones are thermoset and cannot be reprocessed like thermoplastics. For the same reason, it cannot be heat-sealed, and when connected, the Cable Sleeve is placed on the hook joint of the hose, and is fastened with two straps from opposite directions to fix the hose. Co-molding is sometimes used in the medical device field.
Pet Velcro Braided Sleeve Appearance and Mechanical Properties: Compared to some organic thermoplastics, the transparency of silicones can best be described as "translucent". This result is due to the fact that the silicone elastomer from which the hose is made consists of a silicone polymer and amorphous silica. All PET Velcro Braided Sleeve are translucent because the two materials have different indices of refraction and there is no specific way to mix them to match.
After curing the PET Velcro Braided Sleeve, the silicone elastomer exhibited meaningful mechanical properties, which included moderate hardness and high elongation at break, but lower tensile strength than polyurethane (PU). They have a tacky surface and a higher coefficient of friction than polytetrafluoroethylene (PTFE), but are much less rigid. Being hydrophobic, they are excellent electrical insulators, attract dust, and they have a greater operating temperature range than PVC.
