The hottest TPE soft rubber material has excellent

The excellent properties of TPE soft rubber material have an impact on traditional PVC materials

the development of raw materials plays a vital role in its downstream end products. In recent years, the TPE product market in foreign developed countries and regions is also growing at a very alarming rate, which has a great impact on the traditional PVC industry

because TPE has a very wide range of applications, is relatively easy to process, can be recycled and processed, and has many characteristics such as energy saving and environmental protection, it is also more and more welcomed by the majority of users. At the same time, many industries are gradually replacing traditional rubber raw materials with TPE materials

as we all know, gas masks are a kind of product born because of the production of chemical weapons. At first, gas masks were a kind of protective equipment aimed at toxic gas to protect personal respiratory tract. Nowadays, the material of gas masks has been changed from ordinary PVC rubber to silicone rubber and thermoplastic elastomer TPE

there are various styles and designs of gas masks on the market, and most of the structures are made of hard plastic and soft rubber materials. Hard plastic generally refers to thermosetting plastic, which is generally processed by hot pressing and cannot be processed again after molding. Generally speaking, hard plastic is a kind of raw plastic, which has a hard feel, but is not very durable. In addition, in the gas mask cover, the use of hard plastic increased by 18.2% year-on-year; Gross profit of 4.713 billion yuan to support the mask, so that the air can be effectively circulated; The soft rubber material is made of plastic through injection molding. It feels soft at room temperature. It is precisely because the soft PHA material makes people wear gas masks and have a certain sense of comfort when they contact the human body. With the birth of TPE material, there are two materials used in the production process of gas mask cover, one is silica gel, and the other is environmental friendly and non-toxic tpe/tpr soft rubber material

then silicone and TPE materials are selected as raw materials for gas mask cover. The main factors are as follows:

first, environmental protection, non-toxic, and safety

silicone is a highly active adsorption material. The color of silicone rubber is white and opaque. It is an amorphous substance, insoluble in water and any solvent, non-toxic and tasteless, with stable chemical properties. It does not react with any substance except strong alkali and hydrofluoric acid. High adsorption performance, good thermal stability and stable chemical properties

tpe not only has the high elasticity, high strength and high resilience of rubber, but also has some characteristics of injection molding. It not only has the characteristics of environmental protection, non-toxic and safety, but also has a very wide range of hardness and excellent coloring. It not only has a relatively soft touch, but also has excellent weather resistance, fatigue resistance and temperature resistance

second, soft touch

both silicone materials and TPE materials can provide materials with suitable hardness. They can find a balance between the comfort of contact with the face and the strength of the material. Nowadays, gas masks are made of soft rubber and TPE materials, both of which have good low temperature resistance

III. one piece molding

tpe material can be directly adhered to PP material mask by injection molding, and now it becomes a whole, and it can be assembled without the help of adhesive and other pasted supplies. Silicone material has always been suitable for making high-end gas masks, while TPE material is suitable for making middle-end gas masks. Because silica gel material itself has excellent tensile resilience, relatively speaking, TPE material can be 100% recycled and reused by recycling, which can not be achieved by silica gel, PVC and other rubber products
