Appearance: white powder
Relative density (specific gravity): 1.35-1.45
Particle diameter: loose resin: 60-150 mm
It can be burned and degraded in the flame, giving off hydrogen chloride, carbon monoxide, benzene and so on, but it will self extinguish when leaving the flame.

3、 Main uses
PVC resin is one of the largest varieties of synthetic materials. SG-5 is mainly used for hard pipe, monofilament, sleeve, wire, cable, film, sheet, flooring material, artificial leather and sealing material.

4、 Packaging
The modern automatic packaging technology is adopted. The electronic scale is used for automatic measurement: the first type is accurately measured by 25 ± 0.2kg/bag, and the packaging bag is made of three in one composite paper bag, which has good strength, is not easy to be damaged and can prevent moisture. The second type is accurately measured at 800 ± 2kg / bag. Polypropylene container bag is used for packaging bag, which has good strength, is not easy to be damaged, can prevent moisture, corrosion and save cost.

5、 Storage and transportation
澳门六彩网-澳门金六彩资料-今晚澳门六彩开奖结果-澳门六和合资料网站 The product should be stored in a dry and ventilated warehouse and stored separately in batches. It is not allowed to stack in the open air to prevent sun exposure and damp. This product is a non dangerous product and must be transported with clean and covered transportation tools to prevent rain.
