Fumed silicone rubber for extrusion，Is a special for extrusion product development of raw materials, good transparency, extrusion product surface smooth, dry, do not touch; Extruded silica gel in the addition of two two four vulcanizing machine, can be basic processing, extrusion molding, many people do not know what the advantages of gas phase extrusion silica gel? Let's take a look.
1. Characteristics of Fumed silicone rubber for extrusion:
2. The general Precipitated silicone rubber for extrusion will be white when it is stretched, and it can not be pulled for a long time. And the gas phase extrusion silica gel is not the same, how to pull the gas phase silica gel will not be white, and pull the longer will not break.
3 .The appearance of Fumed silicone rubber for extrusion is transparent, and the appearance of silica gel is opaque or translucent.
4. Fumed silicone rubber for extrusion tensile strength, tear strength, elongation is better than precipitation silica gel.
5. The white carbon black produced by gas phase method is expensive. Not easy to absorb moisture. Used as a matting agent in coatings. Precipitated silica is cheap and easy to absorb moisture. Can only be used in rubber, plastic products filling reinforcement.
6. The cost of gas phase extrusion silica gel is higher than that of precipitation silica gel, so the tensile strength and elongation of gas phase adhesive with the same hardness are better than that of precipitation. Its environmental protection index is also high.
Gas phase extrusion silica gel application is also very wide, there are silica gel tube, cable, food-grade silica gel tube, medical silica gel tube, industrial silica gel tube, special-shaped silica gel tube, etc.;
Medical silicone tube is mainly used for medical device accessories, medical catheter, with antibacterial design, to ensure the use of safety; Food grade silicone tube is used for water dispenser, coffee machine guide tube, and waterproof line protection of household appliances. Industrial silica gel tube for special chemical, electrical and other special environmental protection carrier circulation, the use of special silica gel.
