Definition of resin for fiberglass tube raw material:
Resins usually have a range of hardening or melting after heating, and tend to flow under external force when softening. They are solid, semi-solid or sometimes liquid organic polymers at room temperature.
Generally speaking, any macromolecule compound that can be used as raw material for plastic products processing is called resin.
Classification of resins for fiberglass tube raw materials:
Natural resin and synthetic resin
3. Processing methods of raw resin for fiberglass tubes:
(1) Thermoplastic resin: It has the properties of heating softening, cooling hardening and no chemical reaction. No matter how many times heating and cooling are repeated, it can maintain this property.
(2) Thermosetting resin refers to a kind of resin that changes chemically after being heated, hardens gradually, and does not soften or dissolve after being heated.
IV. Resin properties of fiberglass tube raw materials:
(1) Weather resistance: aging test
2) Mechanical properties: depending on molecular structure and use
Molecular structure: - CH3 has good electrical insulation, heat resistance and demoulding performance.
Molecular structure: - C6H5 has good thermal stability
Molecular structure: - CH = CH2 has good curing property and gives coupling property
5. Market application of raw resin for fiberglass tube:
(1) Electrical insulating paint: flame retardancy, heat resistance and wear resistance
(2) Coatings: cohesiveness, weatherability and hydrophobicity
(3) Binder: Adhesiveness
(4) Plastics: insulation and heat resistance
(5) Micropowder and trapezoidal polymer: fire resistance, heat resistance, electrical insulation
6. Common resins:
Silane resin, polyester resin, vinyl ester resin, epoxy resin.
