Two part silicone rubber for making silicone produ...

It is generally admitted that silicone rubber is the raw material for making silicone products. The most common silicone rubber is A+B two part silicone rubber, A is silicone base and B is catalyst, which are mixed by a certain percentage when used. Normally we only need to consider the weight of colloidal, and we ought to think about the weight of other additives in special circumstances. For example, the proportion of vulcanizing agent needs to be calculated according to the total weight of silicone rubber and the silicone oil for pad printing silicone rubber. Here I'll show the two part silicone rubber for making silicone products to you.   The quality factors affecting silicone products: 1. Quality of two part silicone rubber raw material can lead to silicone products difficult to remove edge. The poor quality two part silicone rubber is lack of toughness and its tear strength is also evident deficiencies. 2. The increase of the thickness of silicone products certainly lead to difficulties of dismantling the edge. 3. The curing temperature and curing time are proper for two part silicone rubber for making silicone products. This silicone products easily become brittle as long curing time, while curing time of two part silicone rubber is too short will cause bad effect of vulcanization link, so the sulfide links must be good control.     Silicone products can be divided into three categories depending on the forming process. In other words, there are three methods for making silicone products: A. Molded silicone The second way of making silicone products adopts the molded process. Molded silicone products is sulfured into a solid with high temperature, which is added with solid silicone rubber and curing agent raw materials through the pressure on the vulcanizing machine. The hardness of molded two part silicone rubber is usually 30°C-70°C. Mould shape determines the shape of molded silicone products which is one of the most widely employed in the silicone industry. It can mainly used in accessories, buttons, silicone gifts, silicone hand ring, silicone watches, key bag, cell phone sets, silicone kitchenware, silicone pad, ice, cake mold and so on.   B. Extruded silicone The second approach of making silicone products is extruding molding process with extruding machine. But the shape of the extruding silicone has limitations and the general shape of silicone products is strip and tube which can be cut at random. The silicone products with two part silicone rubber raw material are widely used in medical equipment, food machinery by extrusion molding process.   C. Liquid silicone Liquid silicone products are widely used in the simulation of human organs, medical silicone rubber, breast pad, etc. because of its characteristics of soft and flexibility, the hardness of which can reach 10°C-40°C. Making silicone products is through injection molding process with two part silicone rubber.   D. Special products Special silicone products are made according to the chemical properties of the two part silicone rubber or addition of  some auxiliary materials, which has features of high temperature resistance (up to 330 degrees), food grade (fully comply with FDA, FLGB standard), medical grade, flame retardant grade, luminous, negative ions, discoloration, etc.   Shenzhen Hong Ye Jie Technology Co., Ltd is a professional manufacturer of two part silicone rubber, which has passed through authentication of ISO9001 quality systems.
