HIPS recycled material manufacturers believe that HIPS is an excellent recycled plastic on the market. Its impact strength is very high, more than 4 times higher than abs. Its electrical insulation is also very good, and HIPS is easy to color and print. And HIPS this plastic raw material is hard and brittle, easy to crack, not impact resistant. Therefore, we will use rubber modification to solve the above problems.

The thermal stability of HIPS recycled material is poor, and the heat resistance is not very ideal. Although the impact strength is good, its elongation is smaller than that of ABS, so the screw holes designed on the shell are easily broken by self-tapping screws. In order to solve the problem of its impact resistance, rubber is added to optimize it, but if rubber is added, the gloss of its surface will become dull.

Because the HIPS recycled material contains 5-15% rubber in the molecule, it affects its fluidity to a certain extent. It is better if the injection pressure and molding temperature are higher. Its cooling rate is slower than that of PS, and it requires sufficient holding pressure, holding time and cooling to form. Its molding cycle will be slightly longer than PS, and the processing temperature will generally be kept at 190-240. HIPS products made of plastic materials have a particular "white edge" problem. By increasing the mold temperature and clamping force, reducing the holding pressure and time, the water mark in the product will be more obvious.

At present, there are more than a dozen waste plastic processing and distribution centers in various parts of China, and most of the transactions are in the hundreds of millions. Therefore, the waste plastic processing and recycling industry can be said to be the future development trend, and the trading volume of this industry is also increasing year by year.HIPS recycled materialThe use of plastic raw material enterprises to achieve plastic recycling is also of great significance. Increasing the recycling of waste plastics can not only promote economic development, but also solve the contradiction between plastic development and environmental protection, which can play a very positive role in the environment and economy.
