High Tensile and High Viscosity Modified Nylon 6 Products in Hebei Yancheng

A high-stretch and high-viscosity modified nylon 6 product widely used in the manufacture of nylon tube embryos, casing films, heat shrinkable films and other packaging products, recently successfully developed in Hebei Hengshui Jinlun Plastic Co., Ltd. and put on the market. The production technology has obtained national patents.

According to reports, the product has good physical properties, anti-aging properties and other characteristics, its elongation at break and notched impact strength reached 300% and 29kg/m2 above, the relative viscosity of 3.2 to 4.0 or more, is to produce two-way stretch film Ideal for high toughness tube embryos. The product innovation in technology mainly reflected in the following two aspects: First, a new breakthrough was made in the production process. The new process was added to the vacuum drying polymerization machine with a mixture of normal nylon 6 resin as the main component. The vacuum degree was 0.096 Mpa-0.1. Mpa, temperature 150 °C -210 °C for solid-phase polymerization, and cooling and cooling in succession, vacuum extraction, low molecular weight, resulting in a high tensile and high viscosity modified nylon 6 products. The second is to use resin modified new technology to improve the toughness of the product, and the notched impact strength is increased by 200% compared with the common product. The product has passed the national chemical product quality test, and all the indicators have reached the standards of similar foreign products.
