What is PVC paste resin for gloves?
Polyvinylchloride (polyvinylchloride) abbreviated PVC is a polymer compound formed by the polymerization of vinylchlo-ride monomer (VCM). The degree of polymerization can be controlled by reaction temperature and polymerization molecular weight regulator to control the physical properties and appearance of PVC paste resin: White powder Molecular weight: 40600~111600 Density: 1.35~1.45g/ml Apparent density: 0.4~0.65g/ml Specific heat capacity (0~100℃): 1.045~1.463J/(g. ℃) Thermal conductivity: 0.1626W/ (mk) Refractive index: nD20=1.544 Particle diameter: compact (XJ) type 30~100um loose (SG) type: 60~150um paste resin 1.2~2um softening point: 75~85 ℃ thermal decomposition point: >100-120 ℃ Begin to degrade into hydrogen chloride. Solubility: insoluble in water, gasoline, alcohol, vinyl chloride. Soluble in ketones, esters and chlorinated hydrocarbon solvents. Toxicity: non-toxic, odorless
The so-called viscosity reducer is a popular name, that is, a diluent that reduces the viscosity of the PVC paste resin material. Its real identity is “dearomatized mineral spirits” and divided into three categories: low-boiling mineral spirits, such as 6# extraction mineral spirits, which have a boiling range of 60-90°C; medium boiling point mineral spirits, Such as rubber mineral spirits, the boiling range is 80-120°C; high boiling point mineral spirits, such as paint mineral spirits, the boiling range is 140-200°C.
