Application

PVC is actually a vinyl polymer, and its material is an amorphous material.

Polyvinyl chloride (Polyvinyl chloride), English abbreviation PVC, is a polymer of vinyl chloride monomer (VCM) polymerized by peroxide, azo compound and other initiators or under the action of light and heat according to the mechanism of free radical polymerization. . Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.

PVC is a white powder with an amorphous structure with a small degree of branching. The glass transition temperature is 77~90°C, and it begins to decompose at about 170°C. The stability to light and heat is poor. Above 100°C or after long-term sunlight exposure, it will It decomposes to produce hydrogen chloride, and further autocatalytic decomposition, causing discoloration and rapid decline in physical and mechanical properties. In practical applications, stabilizers must be added to improve the stability to heat and light. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 110,000. It has a large polydispersity. The molecular weight increases with the decrease of the polymerization temperature. , 160 ~ 180 ℃ began to transform into a viscous flow state; good mechanical properties, tensile strength of about 60MPa, impact strength of 5 ~ 10kJ/m2; excellent dielectric properties.

PVC was once the largest general-purpose plastic in the world, and it is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc.

On October 27, 2017, the list of carcinogens published by the World Health Organization's International Agency for Research on Cancer was preliminarily sorted out for reference, and PVC was included in the list of 3 types of carcinogens.

●Stabilizers, lubricants, auxiliary processing agents, pigments, impact resistance agents and other additives are often added to PVC materials in practical use. It has non-flammability, high strength, weather resistance and excellent geometric stability.

●PVC is very resistant to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

●PVC is very resistant to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. In addition, the term person vs computer in the game is abbreviated as PVC, and PVC human figures are often abbreviated as PVC.

●PVC products are actually very common in daily life. Like the credit cards we usually use, its material is PVC. Nowadays, the badges or badges that all large and medium-sized enterprises wear are made of PVC.

●PVC has become popular in the market due to its durable, waterproof and wear-resistant properties. And because its material is relatively hard, it is more competitive in the market compared to some plastic-encapsulated products.

●PVC has a wide range of uses. In addition to some home improvement items and the above-mentioned badges, it can also be made into personalized key chains, mobile phone chains, bookmarks, membership cards, admission cards, business cards, product additional gifts, promotions Event promotional materials, exhibition gifts, car interiors, interior accessories, first aid information cards, commodity nameplates, refrigerator stickers, PVC stickers and other products.

●There are many kinds of PVC cards, non-metallic cards include ordinary pvc cards (calendar card, commemorative card, membership card, discount card, VIP card, loyalty card, magnetic stripe card, dining card, scratch card, smart card, door opening card, attendance card card, commemorative card, membership card, discount card), frosted pvc card, transparent pvc card, transparent frosted pvc card, etc. This product has the characteristics of pvc card because it is printed by the printing machine, so the card has the characteristics of color diversity and bright color effect of the pattern. Metal cards include frosted metal cards, laser metal cards, fine-dot metal cards, and metal silver cards.

The difference between electrophoresis gold card and imitation gold card: imitation gold card: the color of the card is dim, and the surface of the card is prone to fading and flooding after a long time. The real gold card was only golden at the time, and it lost its real gold luster over time. Electrophoresis Gold Card: Made with the latest technology, the color is as lustrous as real gold, with a unique three-dimensional relief of relief, the texture is doubled, and the noble grade of the metal VIP card is even more prominent. And can maintain the characteristics of the product will never fade.

Post Injection Molding Process

1. Processing equipment: CNC, WEDM, lathe, milling machine, drilling machine, grinder, etc.;

2. Surface treatment: For some products that require subsequent processing, we can provide surface treatment services to achieve the special purpose of customers. At present, we can provide degreasing, polishing, electroplating (gold, silver, nickel, tin, galvanized, etc.), anodizing, electrophoresis and other surface treatment services for precision parts.

Moulds and Inspection Fixtures

1. Mold service life: usually semi-permanent. (except for lost foam)

2. Mold delivery time: 10-25 days, (according to product structure and product size).

3. Tooling and mold maintenance: Zhongwei is responsible for precision parts.
