Product Description
Material B- Fast Material
Characteristics
Foaming performance-foam dry loose better fluidity, high foaming ratio, pre-hair and molding without bad smell, curing time is short, in the vacuum forming machine cooling speed.
Processing performance-good demoulding, good combination, short cooling time, wide molding range, good melting, smooth and bright surface.
Forming quality-high hardness, good toughness, good strength, bright appearance, especially suitable for the production of packaging cushioning materials and fishing boxes.
Preservation-raw materials and foam can be used for a long time, stable quality.
Environmental protection-in line with the EU ROHS directive, halogen-free, no toxic and harmful substances, to meet the Reach control substances.

Precautions for use
Material B is suitable for all kinds of pre-foaming machine forming machines. Customers can choose different specifications of material B according to different foam product structures and sizes, and can produce EPS foam molding products with excellent quality.
Storage Considerations
1. EPS storage place should be cool and well ventilated. In order to prevent the foaming agent from escaping too fast, maintain a moderate magnification. The storage room temperature is preferably below 25 ℃, and keep ventilated.
2, EPS contains combustible volatile foaming agent, in the storage state will also be alleviated, so the original particles, foam particles or molded products place is strictly prohibited fireworks, static electricity or lightning, so as to avoid danger.
3, raw materials as far as possible first use, keep fresh, in order to obtain stable operating conditions and good products.
