Exploring PVC Resin Powder Grades – Application-Based Guidance from Pangrui Experts

Polyvinyl chloride (PVC) resin powder is one of the most essential raw materials in the plastics industry. Its unique versatility and adaptability make it suitable for a wide range of applications, from infrastructure to healthcare. However, selecting the right grade of PVC resin is critical, as each grade is engineered to deliver specific characteristics and performance outcomes. At Jiangsu Pangrui New Materials Co., Ltd., we offer a comprehensive portfolio of PVC resin powders and help our clients choose the ideal grade for their manufacturing needs.

Types of PVC Resin – Suspension and Emulsion

PVC resin powder is primarily available in two forms: suspension PVC (S-PVC) and emulsion PVC (E-PVC). Each is designed through different polymerization processes and serves distinct application segments. S-PVC is widely used in rigid applications such as pipes and window profiles due to its balanced mechanical strength and processing ease. E-PVC, on the other hand, features finer particle sizes and is ideal for high-precision applications like films, coatings, gloves, and flooring where surface quality and flexibility are essential.

The Importance of K-Value in Resin Selection

One of the most important indicators of PVC resin quality is the K-value, which represents the polymer’s molecular weight and affects both its flow behavior and final product properties. A lower K-value, such as K57–60, results in easier processing and is ideal for transparent films and packaging. Higher K-values, such as K70–80, offer greater strength and elasticity, which are required in flexible and wear-resistant applications like cables and medical devices. Mid-range values like K65–67 are typically used in rigid pipes and fittings, where a balance of stiffness and processability is necessary.

Matching Resin Grades to Applications

Jiangsu Pangrui offers a wide selection of PVC resin grades to suit specific industry needs. For instance, manufacturers of water pipes and electrical conduits often prefer K65–67 grades for their high rigidity and pressure resistance. Builders of window profiles and decorative panels typically use K60–66 grades that combine ease of extrusion with surface finish. In flexible packaging or cling films, E-PVC with a K-value around K58 is preferred for its clarity and softness.

Specialized Applications and Their Requirements

In more specialized fields like wire and cable production, manufacturers benefit from using higher K-value S-PVC or E-PVC that can withstand heat, mechanical stress, and environmental exposure. For flooring and wall coverings, a high-flexibility grade is essential to maintain durability under foot traffic and retain visual appeal. Likewise, in the production of gloves, medical tubes, and toys, high-purity E-PVC with excellent plasticizer absorption is used to ensure softness, safety, and regulatory compliance.

Why Choose Pangrui for PVC Resin Solutions

At Jiangsu Pangrui, our team of material scientists and application engineers is dedicated to delivering not only high-quality PVC resins but also the expertise needed to match the right resin to the right application. We understand that different processing methods—extrusion, injection molding, calendaring, or dipping—require resins with specific particle sizes, porosity levels, and fusion characteristics.

Quality, Certification, and Environmental Responsibility

All of our PVC resin powders are manufactured to meet strict quality standards. We maintain batch-to-batch consistency, conduct rigorous lab testing, and ensure compliance with international certifications such as REACH, RoHS, and ISO. Additionally, we offer eco-friendly and low-VOC formulations to support manufacturers looking to meet sustainability targets without compromising performance.
