What kind of material is liquid silicone rubber (LSR)?

1. A non-toxic, heat-resistant, highly resilient, flexible thermoset material.

2. It is a double liquid fast vulcanizing material with platinum as vulcanizing agent, which can be injection molded.

Large, fast and repetitive mechanical production.

3. LSR products exhibit good thermal stability, cold resistance, excellent electrical insulation, and no harmful substances when burned.

It is a good alternative to plastics.

LSR is an emerging environmentally friendly material, what is the difference from solid silicone?

1. More health and safety

A: peroxide curing

B: Platinum vulcanization system

2. More efficient

3. More labor-saving (no need to mix rubber, preform, feed, trim)

why is liquid silicone rubber (LSR) the safest alternative to plastics?

1.Price problem

Petrochemical materials are all related to petroleum. The main component of LSR is silicon. The most abundant element on earth is silicon, and it is a material that can be recycled repeatedly.

2. Environmental issues

LSR is safe for the environment, degradability

3. Health and safety

Today, LSR is gradually coming down from the altar of high-end products and is accepted by the general public.

Nowadays it is widely used in the production of health products, automobiles, baby products, medical supplies, diving equipment, sports equipment, electric products, kitchen utensils, seals, etc.

LSR molding process

1. LSR is a thermoset material

2. LSR has good fluidity, so the clamping force and injection pressure are not high, but the accuracy of the injection is higher.

3. LSR exhaust is relatively difficult, the exhaust gap is generally 0.02MM. Therefore, the accuracy of the mold is higher.

4. Barrel and feed cooling

5. Screw requires screw with mixing head
