Solid Phenolic Resin 2402, Vulcanizing Agent for Butyl Rubber Phenolic Resin From China

Product description

Bakelite Phenolic resins Powder are synthetic polymers formed as condensation products of phenols and aldehydes. This step-growth polymerization reaction can be either acid- or base-catalyzed. In acid, the reaction forms novolac resins. These resins require a curing agent - often hexamethylenetetramine or hexa.They are not heat-sensitive. In alkaline solution, the polymerization reaction produces resole resins. These resins are sensitive to heat and acids, do not require curing agents, and have relatively short shelf lives.

Phenolic resin is a synthetic plastic, colorless or yellowish-brown transparent solid, because of the use of electrical equipment, also known as bakelite. It has good heat resistance, fire resistance, water resistance and insulation, good acid resistance, poor alkali resistance, good mechanical and electrical properties, and is easy to cut. It can be divided into two categories: thermosetting plastics and thermoplastic plastics. Modified phenolic resins with different functions can be synthesized by adding different components. They have different excellent properties, such as alkali resistance, wear resistance, oil resistance and corrosion resistance.

Application

Used as tackifier for chloroprene adhesives and vulcanizer for butyl rubber.

Storage

Store in a cool, ventilated warehouse. Storage temperature should not exceed 37 C. Keep away from fire and heat sources. Keep the container sealed. It should be stored separately from the oxidant and should not be mixed. Equipped with the corresponding variety and quantity of fire fighting equipment. The storage area shall be equipped with emergency leak handling equipment and suitable storage materials.
