Applications of HTV Silicone Rubber A

Silicone rubber refers to rubber whose main chain is composed of alternating silicon and oxygen atoms, with two organic groups usually connected to the silicon atoms. Ordinary silicone rubber is mainly composed of siloxane chains containing methyl groups and a small amount of vinyl groups. The introduction of phenyl can improve the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can improve the temperature and oil resistance of silicone rubber.

Silicone rubber has good low-temperature resistance and can generally work at -55 ℃. After the introduction of phenyl, it can reach -73 ℃. The heat resistance of silicone rubber is also outstanding, and it can work for a long time at 180 ℃. It can withstand several weeks or more of elasticity even at slightly above 200 ℃, and can instantly withstand high temperatures above 300 ℃. Silicone rubber has good breathability and the oxygen permeability is the highest among synthetic polymers. In addition, silicone rubber also has prominent characteristics of physiological inertness and does not cause coagulation, making it widely used in the medical field

Automotive Industry

HTV Silicone rubber has a wide range of applications, such as in areas such as bushings, cushions, belts, protective covers, caps, sealing rings, etc. near engines and transmissions, which require resistance to temperatures of 175 ° C, and in some places, it even needs to withstand temperatures above 300 ° C. For this situation, ordinary synthetic rubber can no longer meet the demand, so HTV silicone rubber needs to be used.

Aerospace

Aircraft require the use of materials with long-term resistance to ultra-high and low temperatures (-75~200 ° C), ozone resistance, radiation resistance, aging resistance, flame retardancy, and other properties. The HTV silicone rubber products used in these aircraft include various rubber hoses, sealing washers, gaskets, cups, valves, shock absorbers, hot air ducts, switch sheaths, oxygen masks, fire barriers, hoses for instruments and meters, buffer pads, wires, cables, plugs, sockets, switch buttons, etc.

Healthcare sector

HTV silicone rubber has non-toxic properties, good biocompatibility, high temperature resistance, and good physical and mechanical properties, and is widely used in the medical industry. HCR silicone rubber can be used to manufacture blood vessels, various catheters, drainage tubes, cosmetic and repair materials, artificial skin, drug delivery systems, and biosensors. HCR silicone rubber can also be used to manufacture various human organs, such as artificial larynx, artificial lungs, retinal implants, artificial heart spherical mitral valves, esophagus, trachea, artificial joints, and prostheses.
