Hydroxyl-terminated polybutadiene acrylonitrile(HTBN)

Description

Hydroxy-terminated polybutadiene acrylonitrile (abbreviated as hydroxybutadiene acrylonitrile,  HTBN) is a telechelic polymer with butadiene-acrylonitrile as the main chain and a hydroxyl group at the end of the molecular chain. It is a synthetic polymer material with excellent performance and one of the liquid rubber products.

Chemical Composition

HO-[-(CH₂CH=CHCH₂)_X(CH₂=CH)_Y-]- OH

                                                                CN

Key Features

Good oil resistance, adhesion, aging resistance and low temperature resistance.

Nitrile arc glue mainly uses the molecular reaction between end functions and bifunctional groups to extend the chain and then cross-link to form an elastic long-chain polymer.

Typical Properties

Application

Labor protection gloves: Adding to butyl rubber gloves can increase their tensile strength, wear resistance and strength. Adding natural latex protective gloves can enhance the wear resistance and prevent partial frost.

Papermaking industry: used for paper and cardboard printing to improve production efficiency and paper quality. It is suitable for decorative base paper, wear-resistant paper, medium and high-grade copper paper, etc.

Construction industry‌: Used in emerging cement mortars, wood glues, aluminum alloys, etc. to enhance the performance of materials.

Lithium battery manufacturing: As a special latex as a powerful sensitizer for lithium batteries, it has the characteristics of good mechanical stability, strong alkali resistance, and excellent flexibility after film formation. It is especially suitable for manufacturing high-quality lithium-ion batteries and lithium-ion power batteries.

In addition, Amazon-based styrene-butadiene latex also evaluates back adhesives, environmentally friendly jewelry, textiles and other industries to improve the performance and quality of these products

Package, storage and transportation

It can be used as the coating layer or insulation layer of solid rocket motors, and has good mechanical properties;

Adhesives can be made using HTBN for bonding rubber, polyester, and metal. Its characteristic is that it cures at

room temperature without using solvents;

Can produce corrosion-resistant coatings suitable for use in acidic environments;

Toughening agents used in epoxy resins have great potential to expand epoxy resins and can improve their aging resistance.
