What are the Basic Raw Materials of PVC Gloves?

Sep. 18, 2020

As a Non Latex Gloves Manufacturer, share with you. The basic raw materials of PVC gloves are: PVC paste resin, DOP\DINP, solvent oil, heat stabilizer, coloring agent, and filler. 

PVC paste resin

Polyvinylchloride abbreviated as PVC is Vinylchlo-Ride Monomer, the degree of polymerization can be controlled by reaction temperature and polymerization molecular weight regulator Physical properties of PVC paste resin Appearance: 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 ℃ Start to degrade hydrogen chloride Solubility: insoluble in water, gasoline, alcohol, vinyl chloride. Soluble in ketones, esters and chlorinated hydrocarbon solvents. Toxicity: non-toxic and odorless.

Plasticizer

Plasticizers are the largest additives in the modern plastics industry and play a decisive role in promoting the development of the plastics industry, especially the polyvinyl chloride industry. Anything that can be uniformly mixed with the resin without chemical change during mixing, but can reduce the glass transition temperature of the material and the melt viscosity during plastic molding, and it will remain unchanged or undergo chemical changes. However, it can be retained in plastic products for a long time and can change certain physical properties of the resin. Liquid organic compounds or low-melting solids with these properties are all called plasticizers.

 Plasticizers can reduce the elastic modulus and elongation at break Strength, improve elongation and elongation at break, improve flexibility, improve reversible bending strength, improve toughness and impact strength. Lower the glass transition temperature, expand the applicability of the polymer at lower temperatures, improve the adhesion to various base materials, increase or decrease the sealing properties of the film, improve the lubricating performance and reduce friction. Reduce electrostatic charging capacity, improve surface gloss and appearance, plasticizer refers to an organic substance that increases plasticizers for plastics, improves the fluidity of resins during molding, and makes products flexible.

Heat stabilizers

PVC itself has no obvious melting point. It starts to soften at 80 ℃ to 83 ℃, and starts to flow when heated to 180 ℃. Thermal decomposition begins at >120 ℃, so it begins to decompose before reaching the fluidity and melting point, and gradually coking from yellow to black! In this way, there is no way for PVC to make products! The reaction of polyvinyl chloride is a chemical reaction. It is a reaction in which HCl is released after the PVC is heated. According to this reaction, as long as the Hcl is not quickly released, it can prevent the product from turning yellow and zooming during processing. So the heat stabilizer was born, its role is to capture Hcl to prepare dehydrochlorination reaction! Calcium-zinc composite stabilizer, due to its environmental protection, non-toxic, low-toxicity, high-efficiency, lead-free, and cadmium-free development has attracted widespread attention from the country.
