CAS No. 9002-86-2 Sg8 Sg5 Sg3 Polyvinyl Chloride Paste PVC Resin

Product Description

Product Overview

Polyvinyl chloride (PVC) paste Resin , as the name implies, is that this resin is mainly used in paste form. People often use this type of paste as plastisol, which is a unique liquid form of PVC plastic in its unprocessed state. . Paste resins are often prepared by emulsion and micro-suspension methods.
 

 

Key Characteristics

 

Table 1: Classification by Viscosity Grade

Viscosity Grade	Characteristics	Typical Values (Brookfield, 25°C)	Applications

Table 2: Classification by Molecular Weight (K-value)

K-value Range	Characteristics	Applications
Low (K=60-65)	Lower molecular weight, high fluidity	Soft toys, low-strength coatings
Medium (K=65-70)	Balanced strength and processability	Artificial leather, automotive interiors
High (K=70-80)	High mechanical strength, wear resistance	Industrial flooring, foamed products

 

Table 3: Classification by Production Process

Process	Characteristics	Applications
Microsuspension	Uniform particle size, high transparency	Transparent coatings, glossy surfaces
Emulsion	Smaller particles, high flexibility	Elastic seals, complex-shaped products

 

Table 4: Classification by Application Field

Application Grade	Characteristics	Examples
General Purpose	Cost-effective for standard products	Toys, packaging materials
Foaming Specialty	High compatibility with foaming agents	Foamed wallpaper, automotive soundproofing
Medical Grade	High purity, low migration, FDA-compliant	Medical gloves, disposable tubes
Weather-resistant	UV stabilizers added for outdoor use	Inflatable products, automotive coatings

Polyvinyl chloride paste resin has a fine particle size, and its texture is like talc, with immobility. The polyvinyl chloride paste resin is mixed with a Plasticizer and then stirred to form a stable suspension, which is then made into PVC paste, or PVC plastisol, PVC sol, and it is in this form that people are used to process the final Products. In the process of making paste, various fillers, diluents, heat stabilizers, foaming agents and light stabilizers are added according to the needs of different products.
 

Comparison

PVC Resin vs. PVC Paste Resin
