Description:
PET flame retardant masterbatch (polyethylene terephthalate flame retardant masterbatch) is a halogen-free environmentally friendly additive flame retardant masterbatch with high flame retardant efficiency, low loading amount, high temperature resistance, no precipitation, and good processing flow rate. It has the advantages of good property, high compatibility with resin and little influence on the physical properties of products. It is the preferred flame retardant product for polyethylene terephthalate PET on the market.
PET flame retardant masterbatch is a halogen-free environmentally friendly flame retardant product, and its environmental protection is in full compliance with the EU RoHS and REACH directives.
Product Usage:
Can be widely used in various types of spinning, such as polyester filament, polyester staple fiber, artificial wig and safety rope net, and applied to film, stretch film and injection molded parts.
Packing Specification: packed in kraft paper bag, 25kg//bag。

二、 Drying, and other ingredients:
The optimum temperature and time for product drying is 110 ° C / 8-10 hours;
The product should not be used in combination with calcium carbonate, otherwise the flame retardant effect will be affected, and the masterbatch containing calcium carbonate will also affect the flame retardant effect.
三、The Spinning Process Recommendations:
Since the flame retardant component with a relatively small molecular weight is added, the melting point of the PET chip is lowered, so the processing temperature should be lowered by 10-15 ° C after the addition of the flame retardant masterbatch. Please adjust the temperature setting of each zone according to the melting point of the PET material. .
Taking polyester filament as an example, the PET slice has a melting point of 262 ° C. To reduce the intrinsic viscosity drop, the processing temperature is adjusted as follows:
