1. Physical and chemical properties:
1.1 Product brief: HTPB is aliquid teleclawpolymer andatype of rubbers. It reactswith chain extender,cross-linking agent or curative at room temperature or high temperature to formthe thermosetting polymer withthree-dimensional network structure Thisthermosetting polymer has excellent properties such as,good mechanical properties,hydrolysis resistance, acid and alkali resistance, wear resistance, cold temperature tolerance andelectrical insulating.

3. Application: It can be used as a special purpose adhesive, a plasticizer for various solid rubbers, a thermosetting resin modifier, etc. It can be used to prepare HTPB type polyurethane elastomers, electronic and electrical insulation materials, special coatings, sealing materials, and various industrial rubber products.
4. Package; 10L,50L,200Lwhite PE plastic bucket with mouth diameter no less than 100mm.
5. Storage：Storedat cool, dry and ventilate place. The best storage condition is between-20～38℃.Shelf life:12 months. After the shelf life expires, the samples should be re-sampled and re-inspected according to the technical specifications in Part 2, and they can still be used after passing the test.
6. Transportation: Avoid rain,moisture and sun exposure. Don’t mix-transport with strong oxidizer.
