Sanitary fittings polypropylene raw material optimization formula -
100 kg general injection grade homopolypropylene, 2 kg Zeng Gang toughening brightening masterbatch HB2005, direct mixing molding, you can greatly enhance the overall quality of sanitary ware products and injection molding production efficiency.
Good gloss, beautiful appearance
○ good hardness, impact resistance;
○ shrink uniform, small deformation;
○ high yield, high quality.
HB2005 features introduced:
● For molding of PP wall thickness molding products for a long time, can shorten the cooling setting time 50% -100%, shorten the molding cycle of 20% to 30%, a substantial increase in production efficiency;
● improve heat-resistant temperature 20 ~ 25 ℃;
● improve the rigidity of the product 30%;
● improve the surface hardness;
● improve material impact strength;
● enhance the surface gloss products;
● PP products forming cooling to achieve isometric contraction, eliminate warping deformation, to solve the contraction after deformation;
● improve product quality, reduce the production of non-performing products, to provide products with excellent dimensional stability;
● high safety, in line with ROHS certification, REACH certification, FDA certification, GB9685 list, LFGB certification, plasticizer certification;

Process conditions
● In the process of injection molding, PP products that increase production efficiency and shorten the cooling setting time should be adjusted according to the following process:
● The best injection temperature range of 200 ~ 220 ℃, the specific temperature according to customer's own equipment to determine the condition;
● injection pressure and injection speed according to product quality requirements and process to determine;
● Because HB2005 will make the plastic mouth quicken harden, so the packing time is shortened as far as possible without any shrinkage;
● melt time to ensure good dispersion under the premise of minimizing;
● After the end of the melt cooling setting time can be significantly shortened.
