About the wide application of TPU film

Attention when injection molding TPU plastic raw materials: The main reasons for the occurrence of various adverse phenomena in injection molding are the following five points: 1. Caused by the difference in the nature of the plastic material itself, 2. Improper setting of molding conditions such as temperature, pressure, and firing rate 3. Caused by defects in the design or production of the molding die, 4. Caused by poor design of the shape and thickness of the molded product, 5. Caused by improper selection of the injection molding machine and insufficient capacity. In fact, the cause of poor injection molding is not Simple, usually caused by the interlacing of the above factors. The judgment of the bad cause depends on the experience and technology of the operator. The filling process of the mold cavity. It is recommended to consult relevant professionals before processing to reduce loss costs.

TPS thermoplastic starch fully degradable masterbatch

As a natural macromolecule, starch has a wide range of sources, low price, and complete biodegradation. It is one of the most promising green packaging materials. However, because starch is a polysaccharide polymer compound with a large number of hydroxyl groups in the molecule, it can form a large number of intramolecular and intermolecular hydrogen bonds and form complete particles with a microcrystalline structure, resulting in its melting processing temperature is much higher than its thermal decomposition temperature. It has thermoplastic processability, which greatly limits the application of starch. However, when a variety of additives are added to starch, thermoplastic starch (TPS) is prepared under the action of heat and shear force, thereby improving the processing performance and performance of starch, and realizing a wide range of applications such as starch processing and molding.

Biodegradable materials can be roughly divided into two categories according to their biodegradation process:

Semi-biodegradable plastics currently mainly include starch-modified polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, polycarbonate PC, acrylonitrile-butadiene-styrene ABS, triphenyl phosphate TPE, etc. . Studies have shown that starch-based biodegradable plastics enter landfills without exposure to sunlight for biodegradation.

Fields where TPU materials will be applied

TPU is mainly used in shoe materials due to its excellent elasticity and wear resistance. Footwear products containing TPU are much better than ordinary footwear products in terms of wearing comfort, so they are widely used in high-end footwear products, especially some sports shoes and casual shoes.

TPU materials will promote the rapid development of my country's textile and chemical fiber industry

TPU has a wide range of uses in the light textile industry. In addition to being used as shoe material, synthetic leather and TPU film composite fabrics, the use of TPU chips for the manufacture of spandex chemical fiber is an important application field. Spandex (Lycra) is an elastic fiber that is blended with cotton, wool, acrylic, polyester, etc. into yarn, which can be made into elastic clothing such as tights, sportswear, underwear, sweaters, elastic pants, socks, etc. A kind of high-grade chemical fiber material that has been popular outside.

Advantages and disadvantages of LVT floor

The main raw material for the production of PVC flooring is polyvinyl chloride. Polyvinyl chloride is an environmentally friendly and non-toxic renewable resource. It has been widely used in people's daily life, such as tableware, medical infusion tube bags, etc. Its environmental protection is not required. worried.

Overview of Plastic Flooring

At present, PVC sheet floors can be made into two types. One is a homogeneous and transparent floor with the same pattern material from the bottom to the surface. If the surface is burnt or scratched, it can be repaired by waxing with a polishing machine. . The other is a composite type in which the top layer is a pure PVC transparent layer and then a printing layer and a foam layer are added on the bottom. It can be seen that the same quality transparent material is much better than the composite type.
