详细内容
PP增硬防收缩耐热母粒
本产品主要应用于hdpe，pp工程塑料注塑制品，使制品表皮光洁，无凹凸痕，改善注塑件由于冷却造成收缩不均匀的问题，减少收缩变形，提高尺寸稳定性，尤其是针对高精度塑料制品有显著作用。可通做成产品后产品拿去130高温烘半小时不变型，不收缩。目前市场上很多注塑厂家在注塑产品时，成型时产品出现不同程度收缩，从而影响制品品质。对注塑不是很了解的人都知道这是模具的问题或是原料收缩率大的问题。因为模具复杂，注塑压力在模腔内必然会减少，在复杂型腔内由于压力不够加上物料冷却时的收缩，必定会使制品出现缩水、收缩变形等问题。如果这时去改模具，另开一套模的成本也很大，况且开了模后也不知能不能解决问题。添加防收缩剂，利用它在注塑型腔内膨胀就可以解决缩水、收缩难题。传统收缩剂虽起到抗收缩作用，但制品表面起花纹，影响观感，我司防收缩剂不但能起到抗收缩的作用，而且不影响制品表面光洁度，不影响制品其他物理性能。
应用特点：
1.与树脂相容好，降低分子间摩擦力，缩短生产周期成品率高。
2. 根据塑料制品的厚度来调整用量，方能发挥佳效果，一般添加量在2%-4%。
3. 本品不影响塑料制品的各种物性指标，同时对颜色亦无影响,表皮光洁。
4. 可以提高PP制品的抗冲击和提高热变形温度。
5. 本品属于环保产品，无毒，无害。通过FDA食品认证。
6. 产品包装：25千克/袋。PP hardening shrinkage - resistant masterbatch
This product is mainly used in hdpe, pp engineering plastic injection molding products, make the product skin smooth, no bump marks, improve injection molding parts due to cooling caused by uneven shrinkage, reduce shrinkage deformation, improve dimensional stability, especially for high-precision plastic products have a significant effect. Can be made into a product after the product is taken to 130 high temperature bake for half an hour without deformation, shrinkage. At present, many injection molding manufacturers in the market in injection molding products, molding products appear different degrees of shrinkage, thereby affecting the quality of products. People who don＇t know much about injection molding know that this is a mold problem or a big shrinkage of raw materials. Because the mold is complex, injection pressure in the mold cavity will inevitably reduce, in the complex cavity due to insufficient pressure ａnd material cooling shrinkage, it will make products shrink, shrinkage deformation ａnd other problems. If you change the mold at this time, the cost of opening another set of mold is also very large, ａnd after opening the mold also do not know whether it can solve the problem. Add anti - shrinkage agent, using it in injection molding cavity expansion can solve shrinkage, shrinkage problems. Although the traditional shrinkage agent plays an anti-shrinkage role, but the surface of the product decorative pattern, affect the look ａnd feel, I division I anti-shrinkage agent can not only play an anti-shrinkage role, ａnd does not affect the surface finish of the product, does not affect the other physical properties of the product.
Application features:
1. Good compatibility with resin, reduce friction between molecules, shorten production cycle ａnd high yield.
2. According to the thickness of plastic products to adjust the dosage, can play the best effect, the general amount of addition in 2-4%.
3. This product does not affect all kinds of physical properties of plastic products, nor does it affect the color, ａnd the skin is smooth ａnd clean.
4. The impact resistance ａnd thermal deformation temperature of PP products can be improved.
5. This product belongs to environmental protection product, non-toxic ａnd harmless. FDA food certification.
6. Product packaging: 25kg/bag.
