Application Analysis

As a kind of polymer, PVC is one of the earliest industrialized resin varieties. Compared with other resins, it is low in price, superior in chemical and corrosion resistance, and has its own flame retardant properties, making PVC more and more demanding in modern fields. . PVC is divided into powder and pellets. We have already explained the difference between these two forms. The PVC can also be divided into rigid PVC, soft PVC and PVC paste. Their main application areas are as follows:

1. Application of rigid PVC products
Pipe, can be used for upper water pipes, lower water pipes, gas pipes, infusion pipes and threading pipes.
Profiles for doors, windows, decking, wood, furniture and stair railings.
Sheets, which can be divided into corrugated board, dense board and foam board, etc., used for siding, ceiling, blinds, flooring, decorative materials, furniture materials
And chemical anti-corrosion storage tanks.
Sheets for blister products such as various packaging boxes.
Silk, used for screens, mosquito nets and ropes.
Bottles, packaging materials for food, medicine and cosmetics.
Injection molding products, pipe fittings, valves, office supplies casings and electrical housings.

2. Application of soft PVC products
Film, agricultural greenhouse film, packaging film, daily decorative film, raincoat film and film
Cable for medium and low voltage insulation and sheathed cable materials.
Footwear, soles and face materials, such as rain boots, sandals and cloth soles.
Leather, artificial leather, floor leather and wallpaper.
Others, soft transparent tubes, records and gaskets.

3. Application of PVC paste products
Used in various leathers such as artificial leather, flooring and wallpaper, latex products such as gloves, toys and gaskets.

Production and sales analysis

In the past three years, with the joint influence of national safety inspection, environmental protection inspection and industry supply and demand structure, from July 2016, PVC prices have risen sharply. In 2017, although the price of PVC powder fluctuated, it remained at a high level throughout the year. The average annual price of calcium carbide method is about 6,600 yuan, and the average price of ethylene PVC is about 7,000 yuan. Affected by cost support, resumption of production equipment, new production capacity, and increased inventory of manufacturers, the price of paste resin fell from a high level in 2017, but the average annual price remained at around 8,000 yuan. In August 2018, the ex-factory price of domestic high-end ethylene PVC resin powder reached 7500 yuan/ton, and then fluctuated and fell. The ex-factory price was maintained at around 7000/ton in early November, which was in the stage of shock consolidation.

In terms of domestic production and sales, the national PVC production capacity (including powder and paste) in 2018 is about 25 million tons/year, and the output in January-October is about 19 million tons. The annual production is expected to be 18 million tons. In 2000, the apparent consumption of domestic PVC was expected to be 19.2 million tons, which was basically the same as the output. Therefore, the price of PVC resin powder was maintained at a stable level.

Analysis of PVC modified environmentally friendly pellets
In addition to resin powder as the main raw material in the production of hard transparent environmentally friendly PVC pellets, it is also necessary to add stabilizers, impact modifiers, slip agents, reinforcing agents, anti-UV anti-aging agents, pigments, etc. The enhancement of consciousness and the effect of de-capacity, in addition to the high price of PVC resin powder, the increase of other additives is even greater, resulting in an increase in production costs. As a manufacturer of PVC pellets, Jiahong Plastics specializes in the R&D and granulation production of PVC series blends. It has rich experience in the production of hard transparent environmentally friendly PVC pellets and has obtained a number of patents. The products are: transparent packaging. PVC pellets for containers; transparent series of PVC pellets for medical devices, pellets for co-extrusion (coating) of PVC sheets and profiles; series of pellets for PVC pipe fittings; engineering plastics series modified with PVC substrates; PVC black conductive series of pellets; color mixing container blown special PVC pellets; IC electronic packaging tube special PVC pellets; supermarket shelf label strip special PVC pellets; heat shrinkable label (packaging) membrane PVC pellets; special PVC colored soft Special pellets for quality injection molding; special soft transparent extrusion special pellets; PVC sheet extrusion board (sheet) special pellets; two-color co-extruded window profiles PVC pellets, etc., various transparent hard products based on food packaging grade Health standards (FDA certification), most of the product series can meet the requirements of ROHS and REACH. The PVC pellets for medical devices have passed the GB15593-1995 standard test and are widely praised at home and abroad. Domestic and foreign customers come to negotiate and guide!
