Жидкая фенольная смола

Phenol formaldehyde resins (PF) or phenolic resins are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite, PFs were the first commercial synthetic resins (plastics). They have been widely used for the production of molded products including billiard balls, laboratory countertops, and as coatings and adhesives. They were at one time the primary material used for the production of circuit boards but have been largely replaced with epoxy resins and fiberglass cloth, as with fire-resistant FR-4 circuit board materials.
There are two main production methods. One reacts phenol and formaldehyde directly to produce a thermosetting network polymer, while the other restricts the formaldehyde to produce a prepolymer known as novolac which can be moulded and then cured with the addition of more formaldehyde and heat. There are many variations in both production and input materials that are used to produce a wide variety of resins for special purposes.

Automotive & Transportation
1 Resins for rubber product to improve reinforcement, vulcanization and formability
Resins for rubber reinforcements, tackifiers for synthetic rubber, vulcanizing agents of rubber and adhesives are widely used in automotive, railways and aircraft industries offering high performance and high reliability.
The main applications are tires, belts, and any other rubber applications (tackifiers have good compatibility with various rubbers).
2 Resins for friction materials with superior heat resistance and good adhesive performance.
We offer phenolic resins as binder for friction materials with superior heat resistance and adhesive performance which are used for brake linings, disc brake pads, clutch plates, clutch facing of transmission and others applications like brake shoe for train, Friction Materials for industrial brake

Electrical & Electronics
1 Resins for copper coating and brush binder
ZT insulation resin coating allows thin coating layer within high Tg for any copper insulation - rotor, stator, wire coating. Brush binder products give high heat resistance and high voltage insulation
2 Components
ZT resins used in condensers (ceramic, film) and copper wire coating.

Building & Construction, Industrial
1 Abrasives
ZT provides resins within high quality standards. These resins have an excellent adhesion to textiles and increased wetting properties. Our resins formulations include additive for "Loading glazing reduction".
2 Refractory
ZT resins are used as binder for manufacturing various carbon refractories. Produced within high quality standards they have increased wetting properties and high KDF.
3 Coatings
ZT resins are used as coating within various industries including food packaging. Produced within high quality standards they have increased chemical resistance, improved adhesion to metal and FDA compliance.
4 Foams
ZT phenolic resins are used for the manufacturing of foam for thermal insulation. The foam produced has closed cells which provide excellent insulation values. Phenolic foam also provides 'by nature' very high heat and fire resistance and low smoke emissions.
ZT phenolic foam for floral application, is an 'open cell' foam which allow absorption of a high amount of water that will be retained for a long time.
5 Laminates
ZT phenolic resins are used as binder for the manufacturing of wood and electrical laminates.
6 Foundry
ZT phenolic resins are used as organic binders in foundry.
7 Adhesives
ZT resins are used as adhesives in various industries.
