PB-210
|
Features and main uses：
|
|
PB-210 is a kind of isophthalic unsaturated polyester resin, which has high reactivity and excellent colorability. Its products have good surface gloss, high flatness, low shrinkage, high mechanical strength and good chemical resistance. Pb-210 is BMC resin for injection molding, and PB-987 is its low shrinkage resin. Both of them are used in the field of air conditioner, washing machine and other electrical coil plastic packaging field.

Matters needing attention:
|
|
1. Due to the high temperature in summer, please add proper amount of polymerization inhibitor to ensure the storage stability of BMC.
|
|
2. The product should be stored in a cool place below 25 ℃ to avoid fire and keep away from heat and radiation sources. The shelf life of products stored below 25 ℃ is 3 months.
