Choose first grade resin powder production, not second grade raw material production.

Secondly, for those produced using butyl ester instead of methyl ester, the difference in raw materials results in a cost difference of 20000 yuan per ton, and the quality of the finished product is even worse.

Thirdly, choosing the seasonal formula instead of the generic formula, as the formula changes with the season, is the key to ensuring quality.

Fourth, choose products with transparent colors, flat ends without visible burrs, good toughness, and do not choose products with dark or dirty colors that are prone to breakage.

Fifth, it is better to choose stabilizers that emit a normal plastic odor, while those with a strong odor are often of poor quality and stability. Stabilizers determine the quality standards of the product.

Sixth, choose manufacturers with a large scale and the ability to ship in large quantities, most of which have relatively stable technical processes.
