If we want to select the most environmentally friendly member of the silicone material family, two-component liquid silicone rubber has almost no competitors. The reason is simple: its cross-linking reaction does not produce any by-products. Traditional high-temperature vulcanized silicone rubber releases small molecule by-products during the vulcanization process, which require secondary baking to remove residues; The hydrosilylation reaction of LSR is 100% atom efficient, with each atom of component A and B participating in crosslinking. After the reaction, there are no volatile substances in the system.

This brings two direct environmental advantages. The first is zero waste. The flash rate of LSR injection molding is less than 0.1%, while the flash rate of traditional rubber is usually between 5% and 15%. Flying edge means waste of raw materials and energy consumption in subsequent processing, and LSR has almost reduced this consumption to zero. The second is the low-carbon emissions brought by long lifespan. The service life of LSR products is usually three to five times that of ordinary rubber. Taking baby pacifiers as an example, LSR pacifiers can be used for more than two years without aging or yellowing, while ordinary rubber pacifiers need to be replaced after six months. Less replacement frequency means less production and less waste.

LSR also has an overlooked environmental attribute: recyclability. Although cross-linked LSR cannot be directly remelted, it can be reduced to silicone oil monomers through chemical degradation technology and reintroduced into the production cycle. At present, research has achieved a recovery rate of over 90%, which is almost unique in thermosetting elastomers.

Under the dual pressure of the "dual carbon" target and the EU's green new policy, the environmental attributes of materials are shifting from bonus points to entry barriers. LSR, with its four advantages of zero by-products, zero waste, long lifespan, and recyclability, is becoming the most certain elastomer solution in the transition to green manufacturing.
