What is Liquid silicone rubber?


Liquid silicone rubber is a high purity platinum cured silicone with low compression set, great stability and ability to resist extreme temperatures of heat and cold ideally suitable for the production of parts, where high quality is a must.

Injection molding of liquid silicone rubber

Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume.
Liquid silicone rubber is a high purity platinum cured silicone with low compression set, great stability and ability to resist extreme temperatures of heat and cold ideally suitable for the production of parts, where high quality is a must. Due to the thermosetting nature of the material, liquid silicone injection molding requires special treatment, such as intensive distributive mixing, while maintaining the material at a low temperature before it is pushed into the heated cavity and vulcanized.
Chemically, silicone rubber is a family of thermoset elastomers that have a backbone of alternating silicon and oxygen atoms and methyl or vinyl side groups. Silicone rubbers constitute about 30% of the silicone family, making them the largest group of that family. Silicone rubbers maintain their mechanical properties over a wide range of temperatures and the presence of methyl-groups in silicone rubbers makes these materials extremely hydrophobic.
Typical applications for liquid silicone rubber are products that require high precision such as seals, sealing membranes, electric connectors, multi-pin connectors, infant products where smooth surfaces are desired, such as bottle nipples, medical applications as well as kitchen goods such as baking pans, spatulas, etc. Often, silicone rubber is over molded onto other parts made of different plastics. For example, a silicone button face might be over-molded onto a Nylon 6,6 housing.

Natural rubber & Synthetic rubbers

图片
Natural rubber Natural Rubber - Solid state Natural rubber is made from a runny, milky white liquid called  latex  that oozes from certain plants when you cut into them. (Common dandelions, for example, produce latex; if you snap off their stems, you can see the latex dripping out from them. In theory, there's no reason why we couldn't make rubber by growing dandelions, though we'd need an awful lot of them. Although there are something like 200 plants in the world that produce latex, over 99 percent of the world's natural rubber is made from the latex that comes from a tree species called  Hevea brasiliensis , widely known as the rubber tree . This latex is about one third water and one third rubber particles held in a form known as a  colloidal  suspension. Natural rubber is a polymer of isoprene (also known as 2-methylbuta-1,3-diene) with the chemical formula (C 5 H 8 )n. To put it more simply, it's made of many thousands of basic C 5 H 8 units (the mon

Types of Liquid Silicone Rubber

Silicone rubbers are man-made polymer materials that have a wide range of industrial and manufacturing applications. The various types of silicone rubbers include room temperature vulcanize, liquid silicone, fluorosilicone and high-consistency rubber. In this post, we’ll provide information about liquid silicone rubber, including what it is and the types that are available for manufacturing purposes. WHAT IS LIQUID SILICONE RUBBER? Liquid silicone rubber (LSR) is classified as an elastomer, which means it possesses exceptional elasticity (ability to resume its normal shape after stretching). Key LSR attributes include hardness, tensile strength (resistance to break under tension) and compression set. Other LSR characteristics include excellent bacteria resistance and hydrophobicity, meaning that it acts as a water repellent. The two liquid silicone rubber types include food grade and medical grade. WHAT IS FOOD GRADE LSR? Food grade liquid silicone rubber is well-suited for

An Introduction About Plastic And Marrin Litter

Plastic is present everywhere around us – its durability, low cost, light weight and easily modified shape and properties has led to almost exponential increase in production since its large-scale manufacturing started in 1950s. Nowadays the global annual production of plastics exceeds 311 million tons and it is expected to rise year after year. Plastic is a synthetic material consisting of polymers, which form the basic structure of plastic. This structure can be modified to fulfil different needs by using additives that for example improve the flexibility or strength of the material. The wide variety of different plastics have their unique properties which make them suitable for different applications, e.g. packaging or insulation. Marine litter includes all anthropogenic material that has been entered the marine environment by intentional or unintentional actions of human beings. The composition of marine litter varies between locations, but usually most of the litter consists of p
