Testing of plastic raw materials 1. ABS plastic raw material (acrylonitrile-dibutylene-styrene) Styrene hot melt plastic. Hard plastic materials are opaque. Yellow flame, black smoke, water droplets burning, sour, rubber burning smell, the proportion of 1.04. Soluble in acetone, dichloroethane and three bromomethane. Slow burning, acid and alkali resistant, but stress cracking occurs when exposed to certain acids and organic solvents. Main uses: toys, casings, daily necessities; features: hard, not fragile, can be pasted, but may appear when damaged. Designed for use: mostly for toy shells or unstressed parts. 2. PC plastic raw material (polycarbonate) Engineering plastics have high hardness, high impact strength and high temperature mechanical properties. Hot melt plastic material, not easy to burn. Yellow flame, automatically extinguished. It has a faint phenolic odor. Melting point 430F, specific gravity 1.2. Soluble in methane chloride and ethane chloride. Optical clarity or tint formulations are suitable for lenses, goggles, electrical enclosures, hard hats and engineering equipment. 3. PE plastic raw material (polyethylene) Natural milky white, waxy; it burns fast, like a drop of wax. The flame is blue, the tip is yellow, with the smell of burning paraffin; the melting point of low-density polyethylene is 221f, the melting point of high-density polyethylene is 248F, and the ignition point is 645f; the specific gravity is less than 1, floating on the water; Soluble in cooked benzene and toluene, insoluble in other general solvents. 4. PP plastic raw material (polypropylene) Harder than PE steel; yellow sharp blue flame burns slowly, smell similar to diesel and toxic smoke; melting point is about 334f; specific gravity is 0.906, floating on water, soluble in hot benzene; main uses: toys, daily necessities, packaging plastic bags, bottles; its characteristics: good elasticity, strong toughness, good ductility, but not easy to bond.

PU how to prevent carbonization

PU how to prevent carbonization

2022-12-22

Antibacterial TPE is the abbreviation of Thermo plastic Urethane, and its Chinese name is thermoplastic polyurethane elastomer. Because TPU has the characteristics of high tension, high tension, toughness and aging resistance, it is widely used in medical and health, electronic appliances, industrial and daily necessities, and is a mature environmental protection material. According to the processing method can be divided into injection molding grade, extrusion grade, blow molding grade TPU. In the production and processing, the normal processing temperature of TPU is between 170-220 degrees, which belongs to the heat-sensitive material after being decomposed into flowing water at high temperature, and the adhesion to metal is strengthened, which is very troublesome for cleaning after carbonization. The production temperature is also very limited, many in the processing of TPU materials have encountered carbonization problems, most of them will be cleaned by dismantling the screw. Dismantling the screw is a common method for many companies at present, but there is actually a simpler method when the manpower and material resources are so high. Screw cleaning material also came into being. In view of the problem of TPU black spots, TPU special screw cleaning material can be used for cleaning, and the chemical active substances added in the plastic can be fully released within a certain temperature and time, so that the resin adhering to the surface of the screw and the barrel can be separated from the metal surface, and then brought out by the rotation of the screw, which is convenient, simple and quick to use. Welcome to discuss together

TPU is different in elastomer products.

TPU is different in elastomer products.

DONGGUAN JAHA PLASTIC MATERIAL CO., LTD For TPE and TPU, they are two common types of thermoplastic elastomer materials, these two materials have similarities in performance, but in the basic characteristics are more reflected in their own characteristics, which also provides more possibilities for the choice of materials. What are the differences between TPE and TPU in terms of characteristics? The differences between TPE and TPU in elastomer products are as follows: Transparency: The transparency of TPU is better than that of TPE, and it is not as easy to stick as transparent TPE. Oil resistance: TPU oil resistance is better, and TPE to achieve oil resistance is a certain degree of difficulty. Proportion: The proportion of TPE varies widely, from 0.89 to 1.3, while TPU is between 1.0 and 1.4. In fact, they are used in the process, mainly in the form of blends, so the proportion of large changes. Temperature resistance: TPE is -60 degrees Celsius to 105 degrees Celsius, TPU is -60 degrees Celsius to 80 degrees Celsius. The difference between TPE and TPU in elastomer products will be explained here. TPE can be regarded as the general name of all thermoplastic elastomers. TPU is thermoplastic polyurethane elastomer. From this perspective, TPU is only one of thermoplastic elastomers TPE.
