Product Description

  

Product Description

 

   

PVC resin, with the full name of polyvinyl chloride resin, is a kind of synthetic plastic polymer with large production volume each year. As a result, it is widely used in various plastic industrial fields. Polyvinyl chloride resin is a thermoplastic polymer compound formed by polymerization of vinyl chloride monomer(VCM) or dichloroethane(EDC) under the action of an initiator. Its main component is polyvinyl chloride. Meanwhile, adding some additives to enhance its heat resistance, toughness and ductility. Because of the characteristics of good chemical stability, corrosion resistance and water resistance, polyvinyl chloride is the most widely used raw material in plastic production. 

Before using PVC Resin to make finished products, we should convert it into compounds first by adding additives. As we all know, commonly used additives are heat stabilizers, UV stabilizers, plasticizers, heat modifiers, flame retardants, bactericides, foaming agents, etc.

What is PVC K-value

In brief, the K value is an index indicating the polymerization degree and molecular weight of polyvinyl chloride. In addition, the viscosity number is also an indicator of the molecular weight of the polymer. Since this product is an amorphous linear polymer compound, it is with various different characteristics. The larger the relatively molecular weight, the higher the viscosity, the better the strength, stiffness, toughness, heat and low temperature resistance of the material, but the worse the molding processability. On the whole, the difference in K value of polyvinyl chloride resin will have a certain impact on the processing technology and product performance. Therefore, when purchasing polyvinyl chloride resin, customers need to choose the suitable grade depends on the K value and applications.

By comparison, K70-75 PVC resin with high K value and higher molecular weight has the best mechanical properties. But it is more difficult to process.

In general, PVC resin k65/k66, PVC resin k67/k68 with suitable K value have a good balance between mechanical properties and processability. So they are the most popular and can meet the needs of the most PVC applications.

Compared to other types of PVC resin, K58-60 polyvinyl chloride with low value has the lowest mechanical properties and the processing is easiest. However, it has many difficulties in the application process.

What Are the Differences Between PVC Resin and PVC Paste Resin

• From the physical state, polyvinyl chloride paste is in the form of white fine powder. While the PVC resin is in the form of white fine particles.
• In terms of usage method. When using PVC paste resin to produce some products, you'd better mix it with appropriate amount of plasticizer. Additionally, it is in the form of liquid plastisol sometimes. Paste PVC resin is suitable for the production of flexible plastic products. Polyvinyl chloride resin is used after granulation with an appropriate amount of plasticizer. And it is generally suitable for the production of rigid plastic products.

APPLIACTION

As an important plastic material, PVC resin is widely used in modern industry and life. This resin can be processed into various plastic products, which can be divided into soft and hard products according to their uses. They are mainly used for the production of transparent sheets, pipe fittings, gold cards, blood transfusion equipment, soft and hard pipes, plates, doors and windows, Profiles, films, electrical insulation materials, cable sheaths, blood transfusion
materials, etc. The following are the specific applications of PVC resin:

Construction field
Pipes and tubes. PVC resin is often used in construction to make pipes and tubes, such as drainage pipes. This is due to its excellent aging resistance, high impact strength and toughness, and relatively low price. PVC pipes account for about 20% of the total consumption of PVC in the construction field.
Door and window frames. PVC profiles are the largest area of PVC consumption in my country, accounting for about 25% of the total PVC consumption. and are mainly used to make doors and windows and energy-saving materials.
Floor materials, wall coverings, roofing materials, etc.PVC resin is also used to make floor materials, wall coverings and roofing materials.

Packaging field
Food, cosmetics, and pharmaceutical packaging.  This resin is widely used in the packaging field, such as food packaging films, bottle cap seals, cosmetic packaging boxes, etc. It has good transparency, corrosion resistance, and weather resistance, which can effectively protect products and extend shelf life.

Electronic and electrical fields
Wire and cable insulation.PVC resin has excellent electrical insulation and is widely used in the insulation layer of wires and cables.
Electrical component housing. PVC resin is also used as the housing of electrical components to provide protection and insulation.
Electronic connectors and plugs. Connectors and plugs made of PVC resin have good durability and stability.
Daily necessities
By using an extruder, PVC resin can be extruded into hoses, cables, wires, etc.
Using an injection molding machine with various molds, it can be made into plastic sandals, soles, slippers, toys, auto parts, etc.

Other industrial applications
Film manufacturing. After PVC is mixed with additives and plasticized, it can be made into transparent or colored films of specified thickness, which are
used in greenhouses, plastic greenhouses, packaging and other fields.
Sheets and hard materials. After adding stabilizers, lubricants and fillers to PVC, it can be made into hard sheets and special-shaped tubes of various thicknesses, which are used to make various chemical-resistant storage tanks, air ducts and containers.

Medical field.
PVC resin is also used in the medical field, such as blood transfusion equipment.
