TPE/TPR is also known as synthetic rubber or synthetic rubber. It is a physical mixture of copolymers or polymers, consisting of materials with both thermoplasticity and elasticity.

Its products have the excellent properties of traditional cross-linked vulcanized rubber in terms of the high elasticity, aging resistance, and oil resistance, but also have the characteristics of easy processing of ordinary plastics and wide processing methods.

It can be produced by injection molding, extrusion, blow molding, and other processing methods, both simplify the processing process and reduce processing costs, so thermoplastic elastomer TPE / TPR material has become the latest material to replace traditional rubber, its environmental protection, non-toxic, comfortable to the touch, exquisite appearance, making the product more creative.

TPE is naturally latex-free and is safe for people who are sensitive or allergic to latex.

Therefore, it is also a more humane, high-grade new synthetic material, but also the world’s standard environmental protection raw material, more and more global brands are replacing PVC products with TPE products.

Silicone rubber is an inorganic polymer formed by silicon (Si), oxygen (O), carbon (C) and hydrogen (H). The main chemical chain called the backbone, is formed by silicon and oxygen, called siloxane. To achieve its final characteristics, catalysts are added during the curing process creating a chemical bond between the backbones called crosslinks. Platinum and peroxide are two chemicals used in this curing process, LSR is a platinum-cured silicone rubber.

Platinum-cured silicone rubbers offer benefits over peroxide-cured silicone rubbers including improved tensile strength and tear strength, clarity and consistency, and do not leave behind peroxide residue.

LSR properties:
Biocompatibility: Under extensive testing, liquid silicone rubber has demonstrated superior compatibility with human tissue and body fluids and is hypoallergenic, making it a good choice for skin-contact products. In comparison to other elastomers, liquid silicone rubber is resistant to bacteria growth and will not stain or corrode other materials.

Tasteless and odorless: LSR is tasteless and odorless and can be formulated to comply with stringent FDA standards required for food and beverage and baby products.

Durable: Liquid silicone rubber parts can withstand extreme temperatures, making sex toys easy to clean and store.

Chemical resistance: Liquid silicone rubber resists water, oxidation, and some chemical solutions such as acids and alkali. The material can be sterilized via a variety of methods, including steam autoclaving, ethylene oxide (ETO), gamma, e-beam, and numerous other techniques used for medical and healthcare products.

Temperature endurance: Compared to other elastomers, molded silicone can withstand a wide range of high to low-temperature extremes. It will remain stable in temperatures ranging from minus 60 degrees Celsius to 180 degrees Celsius.

Mechanical properties: Liquid silicone rubber has good elongation, high tear and tensile strength, excellent flexibility, and a hardness range most commonly between 5 to 80 Shore A.

Electrical properties: Liquid silicone rubber also has excellent insulating properties, beneficial for a host of electrical applications. Compared to conventional insulating materials, silicone can perform in far higher and lower temperatures.
