Note
Flame retardant masterbatch and TPU materials need to dry in advance, control the moisture content is lower, the better.Processing conditions as gentle as possible, avoid the degradation of thermoplastic polyurethane raw materials
Packing/Storage
25KG/bag: Transported as a common chemical and stored in dry and cool place, avoid direct sunlight.
