The current concept of daily chemicals consumption is increasingly concerned about the naturalness of products and the safety of raw materials. Consumers often raise concerns and questions about silicon-containing daily chemicals, such as "Will silicon-containing daily chemicals block pores, destroy skin, and damage the body?" and so on.

How many kinds of vulcanization does silicone rubber have? Silicone rubber is generally of highly saturated structure and low curing activity, so it can not be vulcanized with sulfur. The most common curing agent is organic peroxide. Silicone rubber can also be vulcanized by high energy radiation. The vulcanization mechanism of radiation vulcanization is the same as that of peroxide, both of which are cross-linked by free radical reaction.

LED (Light Emitting Diode) is widely used in lighting, display, backlight and many other fields due to its energy saving and environmental protection, long service life, low operating voltage and short switching time. At present, it is developing towards higher brightness, high color, high weather resistance, and high luminous uniformity. The LED industry chain can be divided into upper, middle and lower reaches, which are LED epitaxial chips, LED packaging and LED applications.

In the last issue, we talked about the vulcanization molding of high-temperature vulcanized silicone rubber products: first and second stage vulcanization and its function. So what is the shaping method of the molding and curing of high temperature vulcanized silicone rubber (HTV) products? Today, let me introduce several ways of molding.

You can see all kinds of colorless, colored, square, round, plate and strip products made of high-temperature vulcanized silicone rubber (HTV). It is an elastic silicone rubber product made by synthesizing linear polysiloxane (raw rubber) with molecular weight (400000~800000) from organic silicon intermediate as raw material, adding appropriate reinforcing agent, structure control agent, colorant, vulcanizing agent, foaming agent and other additives t...
