5. Suitable for clean room/clean room/purification workshop/semiconductor, hard disk manufacturing, precision optics, optical electronics, LCD/DVD liquid crystal manufacturing, biomedicine, precision instruments, PCB printing and other industries.

PVC gloves are widely used in labor protection and household hygiene in hygiene inspection, food industry, chemical industry, electronics industry, pharmaceutical industry, paint and coating industry, printing and dyeing industry, agriculture, forestry, animal husbandry and other industries.

Features: PVC gloves are made of polyvinyl chloride through a special process. The gloves are allergen-free, powder-free, low dust generation, low ion content, and do not contain plasticizers, esters, silicone oils and other ingredients. They have strong chemical resistance, good flexibility and touch, and are convenient and comfortable to wear. Anti-static performance, can be used in a dust-free environment.

Grading standards:

Grade A: There are no holes on the surface of the gloves (powdered PVC gloves), uniform powder quantity, no obvious powdery, transparent milky white color, no obvious ink spots, no impurities, and the size and physical properties of each part meet customer requirements.

Grade B products: slight stains, 3 small black spots (1mm≤diameter≤2mm), or small black spots (diameter≤1mm) in large numbers (diameter>5), deformed, impurity (diameter≤1mm), slightly colored Yellow, serious nail marks, cracks, and the size and physical properties of each part do not meet customer requirements.

Waste products: holes, serious oil stains, serious yellowing, impurities (diameter> 1mm), no curling or broken edges, ripped, scratched, torn, cracked, sticky, and leftover materials.

Self-healing products: large amount of powder, large curling, slight dirt, slight internal stickiness, small black oil powder on the fingertips, physical properties are in line with customer requirements.

A grade gloves are allowed to have ≤5 gloves with slight nail imprints, and ≤3 gloves with severe nail imprints are allowed.

Basic raw materials:

The basic raw materials of PVC gloves are: PVC paste resin, plasticizer (DOP\DINP), viscosity reducer (solvent oil), heat stabilizer, coloring agent, and filler.

PVC paste resin:

Polyvinylchloride (polyvinylchloride) abbreviated PVC is a polymer compound polymerized with vinylchlo-ride monomer (vinylchlo-ride monomer) abbreviated as 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 the solubility of hydrogen chloride: insoluble in water, gasoline, alcohol, and vinyl chloride. Soluble in ketones, esters and chlorinated hydrocarbon solvents. Toxicity: non-toxic, odorless


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 changes during mixing, but can reduce the glass transition temperature of the material and the melt viscosity during plastic molding processing, and it remains unchanged, or it can be retained in plastic products for a long time despite chemical changes. It can change some of the physical properties of the resin. Liquid organic compounds or low-melting solids with these properties are called plasticizers. Plasticizers can reduce the modulus of elasticity and tensile strength at break, and improve the elongation and fracture. Elongation, improved flexibility, improved reversible bending strength, improved toughness and impact strength, lowered glass transition temperature, expanded polymer’s applicability at lower temperatures, improved adhesion to various base materials, improved or Reduce the sealing performance of the film, improve the lubricating performance and reduce friction, reduce the electrostatic charging ability, improve the surface gloss and appearance, plasticizer refers to the plasticizer that increases the plastic, improves the fluidity of the resin during the molding process, and makes the product flexible The most commonly used organic substances are phthalate esters such as dioctyl phthalate (DOP) dinonyl phthalate (DINP) and didecyl phthalate (DIDP)

Heat stabilizers:

Polyvinyl chloride (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 turns from yellow to black! In this way, there is no way for PVC to make a product! The reaction of polyvinyl chloride is a chemical reaction. It is a reaction in which hydrogen chloride (HCl) is released after PVC is heated. According to this reaction, as long as the Hcl is not released quickly, 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. Calcium and zinc stabilizers are gradually expanding the market. Calcium-zinc compound stabilizer is non-toxic and environmentally friendly, the price is moderate

Viscosity reducer:

The so-called viscosity reducer is a popular name, that is, a diluent that reduces the viscosity of the PVC paste resin material. Its true identity is “dearomatized mineral spirits” and divided into three categories: low-boiling mineral spirits, such as extractive mineral spirits, with a boiling range of 60-90°C; medium-boiling mineral spirits, such as rubber Mineral spirits, the boiling range is 80-120°C; high-boiling solvent oils, such as paint mineral spirits, have a boiling range of 140-200°C.


PVC can be dyed into various colors. Oil-soluble organic pigments and inorganic pigments are commonly used, and the dosage is about 0.01% to 2% of the resin. Ⅵ. The main function of the filler is to reduce the cost, save the amount of PVC, and improve the performance. Commonly used fillers are calcium carbonate, clay, diatomaceous earth and so on.
