What are the uses of food-grade liquid silicone rubber?

Liquid silicone rubber is a new type of rubber developed on the basis of RTV. It is based on liquid polysiloxane with reactive functional groups at both ends of the molecule, known as "remote claw" polymers.

Liquid silicone rubber has the characteristics of small molecular weight, low viscosity, convenient processing and molding, and can eliminate mixing, pre-molding, post-processing and other processes, easy to realize automation, can save energy and labor, short production cycle and high efficiency. Products made of liquid silicone rubber have the characteristics of high purity, good transparency, low volatile substance content, and has good oil resistance, chemical resistance, aging resistance, light resistance, insulation and thermal insulation, color selection range is wide.

As a typical medical polymer material, silicone rubber's chemical properties, physical and mechanical properties and biological safety have been verified in the field of medical and health applications for 50 years. Liquid silicone rubber (especially molding liquid silicone rubber) as a part of silicone rubber, also plays a role in the field of medical health, body beauty, health care and food.

Liquid silicone rubber in medical treatment and instruments, the use of liquid silicone rubber line shrinkage rate is low (0.3%), good elasticity, curing block in the mouth, plastic deformation is small, can be used as dental impression materials; Liquid silicone rubber can be used to make artificial gills and artificial lungs because of its non-permeability to different gases. Liquid silicone rubber can be used as the repairing material of acoustic lens of B-mode ultrasound probe and the bonding material between acoustic lens layer and matching layer.

Liquid silicone rubber in the application of food related fields, adding molding liquid silicone rubber safe non-toxic, excellent performance, excellent chemical inertia, with high hygiene grade, does not contain nitrosamine and other harmful substances, so that it becomes the first choice of baby products. Using its characteristics of good air permeability, it can also be made into fruit and vegetable fresh-keeping air adjusting film. In addition, liquid silicone rubber is also suitable for food grade applications, such as food containers and distribution devices valves and seals, baby bottle milk, also suitable for the production of food vending machine butterfly valve, baking tray, spatula, silicon mat, etc.
