Transparent TPE/TPR high transparent TPE/TPR product description:
Transparent fraction transparent and translucent series, each with a variety of hardness; Excellent transparency; Smooth and soft surface; Good yellowing resistance, tear resistance and good tensile strength; Meet environmental protection requirements; Applicable to all kinds of transparent series products.
Types of transparent TPE materials:
1. Styrene transparent tpe, which is widely used in footwear industry, has largely replaced rubber; At the same time, its application in industrial rubber products such as adhesive tape and rubber sheet is expanding.
2. Olefin transparent tpe, which has good weather resistance and ozone resistance, is called the fastest growing variety of tpe, and it is mainly called the main rubber material in the fields of automobile and household appliances.
3. diene transparent tpe is an isomer of natural rubber, so it is also called thermoplastic trans natural rubber. Although its heat resistance and mechanical strength are inferior to those of rubber, it is widely used in shoemaking, sponge, optical film and other industrial rubber products due to its good transparency, weather resistance, electrical insulation and photodegradation.
Transparent TPE/TPR high transparent TPE/TPR processing performance main features are as follows:
1. Good weather resistance and good tolerance to ozone, ultraviolet rays and electric arc;
2. Good oil resistance and chemical resistance;
3. High temperature resistance (up to 120℃) and low temperature resistance (-56℃);
4. Good transparency, flexibility and elasticity similar to rubber;
5. High tensile strength, compression deformation resistance and weldability;
6. Extensibility (minimum 500%);
7. Hygiene of medical food (conforming to FDA, TUV and SGS certification);
8. Excellent coloring performance, uniform color dispersion, no flow marks, no fading, excellent extrusion, injection molding and blow molding processing;
9. The process cycle is short, and the materials can be 100% recycled.
Various applications of transparent tpe materials:
Transparent tpe materials have different product properties in different aspects. Thermoplastic elastomer is also called tpe material. Transparent tpe not only has the processing properties of thermoplastic, but also has the physical properties of vulcanized rubber, which is the so-called combination of advantages of plastic and rubber. Transparent tpe is widely used in people's daily life and production.
Transparent tpe of adhesive series has different product performance in different application areas. Transparent tpe materials are widely used:
1. Transparent tpe is applied to the shell, handle and grip of household appliances, which shows a very good hand feeling, has the characteristics of anti-skid, labor saving, easy coloring and processing, and has a wide design space.
2. Transparent tpe materials are used in various paint toys and daily necessities, and have the characteristics of low price, health, safety and environmental protection.
3. Transparent tpe is used in stationery, sports equipment, etc. It has good UV resistance, chemical resistance and easy coloring and processing.
4. Transparent tpe is used in sealing rings, auto parts and handles, which has good shock absorption, compression resistance and electrical insulation.
Tpe is a classical aggregation-inducing molecule, that is, there is no fluorescence in solution, but there is strong fluorescence in solid, so transparent tpe materials have important applications in organic optoelectronics and other fields.
Four good methods to solve the caking of transparent TPE:
The main reason for the caking of transparent TPE is that the material itself is filled with too much oil. Because many manufacturers can only fill more oil in order to achieve OA, if they fill more oil, they will find it easy to agglomerate and trouble us. How to solve the caking problem of transparent TPE?
1. control the temperature well. transparent TPE below 0℃ will still agglomerate after being treated with additives for more than three months. Generally, there is a tendency to agglomerate below 40 degrees.
2. Make transparent TPE underwater. The special anti-sticking agent for TPE is added in the pool to prevent transparent TPE from sticking together. Note: the adding ratio is related to the size of the pool.
3. If the product is caked, you can add some slip agent.
4. If the transparent TPE is caked in the packaging bag, first look at its shape. The cylindrical one is easy to agglomerate. It is best to make it round or oval when granulating, or add some anti-caking agent.
The above four points are good ways to solve the caking of transparent TPE for everyone to learn from. If you have a better method, leave a message to discuss.
