1、Product brief:
Hydroxyl -terminated liquid acrylonitrile rubber (HTBN) is a liquid telechelic polymer with active hydroxyl groups at both ends of the molecular chain, which has the ability to re-react and expand the chain. It is a synthetic polymer material with excellent performance. Due to the introduction of acrylonitrile groups in the molecular chain, besides the general characteristics of hydroxyl-terminated polybutadiene(HTPB), HTBN also has good oil resistance, adhesion, aging resistance, and low-temperature resistance.

3、Application
① Special polyurethane adhesives for bonding various material surfaces.
② Casting, encapsulating for electrical appliances and electrical insulation materials.
③ It can be used as a toughening modifier for thermosetting resins such as epoxy and phenolic resins.
④ It can be used to prepare elastomers, tire conveyor belts and castable rubber products.
⑤ It can be used to prepare oil-resistant and corrosion-resistant coatings.
4、Package:50kg closed head PE white plastic barrel, 200kg iron barrel or customize packaging.
5. Storage:Stored at cool, dry and ventilate place. The best storage condition is between -20~38℃. Shelf life: 12 months. After the storage period 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.
