To be non-toxic, environmentally friendly requirements

- Feb 01, 2018 -

In recent years, China's plastics industry has shown a clear trend of industrial agglomeration, the rapid growth of the number of large-scale enterprises. Industrial structure gradually to large-scale, intensive direction adjustment. Plastic additives industry is also large-scale, intensive direction to adjust, which plasticizers, thermal stabilizers, impact modifiers and processing aids are particularly evident. Active development of "green, environmentally friendly, non-toxic, highly efficient" plastic additives products, is the current plastics additives industry an urgent trend to change.

PC polycarbonate, PP polypropylene in the production of food-grade plastic products, because its own material is non-toxic, and is well known food-grade plastic additive content requirements are very strict, so in the molding process to join the plastic additives is also rigorously tested , And need to achieve non-toxic, environmentally friendly and efficient to be

begging.

Generally in the production of food-grade tableware, straw and other products, the process of forming the basic problems that occur in the following points:

1. Poor fluidity, resulting in increased screw torque, increase equipment energy consumption.

2. Molding surface gloss is not enough, the surface roughness.

Coking occurs after high temperature, resulting in mold release is not smooth.

The silicone masterbatch after many customers to use the test, after adding 0.3% ~ 05% of the proportion of these issues can be basically solved.

Silicone masterbatch in the testing process also ensures food-grade requirements, so that non-toxic, environmentally friendly requirements.
