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 consumer products manufacturing applications. Highly versatile and possessing the ability to withstand extreme temperatures, food grade LSR is an excellent choice for everything from kitchen products such as plastic grips for utensils and cooking tools, ice cube trays and baking molds. Additionally, food grade LSR works well with any industrial equipment that comes in contact with or is exposed to food due to its easy sterilization and compression set.

ABOUT MEDICAL GRADE LSR

Medical grade LSR is a preferred choice of companies in the life sciences-related industries, especially medical device manufacturing. Medical grade LSR enables manufacturers to meet the challenges involved in producing complex, technologically-advanced devices, while improving the quality, lowering the cost and enhancing the durability of the finished product. Devices made from medical grade LSR can withstand the heat, pressure and exposure to harsh chemicals found in many health care environments, while still allowing manufacturers to meet their revenue and profitability objectives.

Natural rubber & Synthetic rubbers

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

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
