DINCH Usage
DINCH can be applied in all kinds of high-class PVC products, like calendering, extrusion, rigid, and half-rigid products. It is recommended for use in children toys, food packaging film, plastic wrap, medical tubes, food-contacted gloves, wall paper, decorative sheet, and medical blood bag, etc.
DINCH is suitable for use with PVC and other polar polymers. It is compatible with all of the monomeric plasticizers commonly used in PVC. In most cases, only minor formulation and processing parameter adjustments are required to process flexible PVC compounds.
Compared to DOP and DINP, DINCH offers improved low temperature performance. In plasticizer applications. It offers lower initial viscosity and better viscosity stability.
Packaging and Shipping
Packing: 200kg/drum or IBC drum
DINCH Storage
Store in a cool, ventilated place indoors, with a storage period of two years.
