Foamed silica gel, also known as addition-type silica gel, is a two-component heating vulcanized silicone rubber. It is composed of silica gel and curing agent at a ratio of 1:1. It is a white or skin-colored oily liquid. After vulcanization, it becomes a soft elastic material, foaming The volume is the original 3-4 to accompany. Next, Qinghe Sanchuang will introduce the foamed silicone strips for you in detail.
The characteristics of raw materials~
1. Advantages:
1. It has excellent high temperature resistance, and the temperature can reach 300 degrees.
2. Food grade, non-toxic and tasteless, passed FDA food grade certification.
3. Soft and elastic, it is a good environmental protection filling material.
4. Foaming ratio: 2-6 times, just at room temperature
5. Finished product density: 200~500kg/M3
2. Purpose:
Silicone foam strip is a silicone product
Because of its non-toxic, environmental protection, UV resistance, high and low temperature resistance (-50 to 250 degrees), high transparency, and strong elasticity, it is widely used in supporting electrical appliances, electronics, furniture equipment, toys, Hardware, medical equipment, sporting goods, audio, lighting, machinery, automobiles, bottle sealing, building curtain wall
Sealing and other industries.
3. Identification method of silicone foam strip:
1. Touch: Silicone foam has resilience, you can touch it directly with your hands to check the elasticity. This is also one of the basic methods.
2. Cut: cut the silicone tube with scissors
, observe carefully and leave it for a period of time, the cut surface part forms a curve, but it is not completely flat. The higher the curvature, the higher the rubber content of the product, and the better the quality. Especially the finished product just out of high temperature vulcanization is more obvious.
3. Combustion: You can cut out a piece, use tweezers or scissors, use a lighter
Or light a match, and observe whether the smoke released from the burning is pure white or mostly white, and then observe whether the ash is white or light gray after burning. The smoke of good-quality silicone foam strips burns and the ash produced after burning is white or gray, with no obvious pungent odor.
