Wood-plastic composite (WPC) is a new type of material compounded by plastic and plant fiber. Among them, the largest output is the composite material with PE and PVC resin as the base material. PE-based plastic-wood composites have excellent aging resistance and are mainly used as outdoor decorative materials. PVC-based plastic-wood composites are light in weight, stable in size, but have relatively poor weather resistance, and are widely used in interior decoration materials. Technology, market, policies and standards help the development of China's plastic-wood composite materials
Plastic-wood composite material is a new type of material that has emerged in large numbers in the past ten years, and has been developed rapidly during the "Twelfth Five-Year Plan" period. The main reasons are
First, the performance of the product has been greatly improved, and tremendous progress has been made in some new process technologies, new raw materials, mechanical molds, post-processing methods, etc., which greatly promotes the mechanical properties and weather resistance of the product. , Appearance and other aspects.
The second is the rapid development of the market, the entire industry has entered a period of rapid growth, and the products have been recognized by consumers with their unique advantages. Especially in some municipal gardens, real estate projects, tourism projects, and home decorations, they are deeply loved by users.
Third, the state has increased its support for plastic-wood composite materials policies, and has successively introduced a series of policies on scientific research and development, taxation and other aspects.
Fourth, product standards are becoming more and more perfect and considerable progress has been made in new product development and new design research. The use of my country's plastic-wood composite material manufacturing technology has reached the international advanced level and greatly enhanced the competition in the international market for products. my country has become the world’s largest producer of wood-plastic composite materials.
In the future, we must continue to work hard to solve the problems of product crease and thermal expansion, and further improve the weather resistance of products, achieve lightweight products, and develop and improve accessories for product installation.
The domestic sales volume of China's plastic-wood composite material market is still lower than the export volume
At present, the large-scale plastic-wood composite material production enterprises in China are mainly exporting, and the main market is in Europe. The North American market was the first to develop, but the barriers to entry were high. Asia and other regions have developed the fastest in recent years.
Compared with the international market, the domestic market is also growing rapidly, but domestic sales are far inferior to exports in terms of shipments. The main reasons are:
First, the domestic market is dominated by engineering construction projects, which require short delivery times and a wide variety of products. On the other hand, the foreign market is dominated by building materials supermarkets, with a large amount of one-time distribution and stable product categories.
Second, domestic sales are affected by low-price competition and are prone to fall into a vicious circle of low prices and low-quality; and domestic sales are difficult and slow to collect payments.
It is expected that China's foreign orders for plastic-wood composite materials from 2016 to 2017 will still maintain an annual growth rate of about 30%
The "13th Five-Year Plan" period will be a period of continuous rapid development of plastic-wood composite materials. The products are more mature and diversified. Some new products, such as PE co-extruded and coated products, PVC foamed quick-installed wall panels, etc., are launched, which will drive the entire industry to develop faster. In the international market, Chinese-made plastic-wood composite materials will occupy a larger market share. In the past year, the entire industry has mainly the following new developments:
1. The market
Although the domestic economic situation is still not optimistic, the plastic wood industry as a whole is still showing rapid growth. According to statistics, the annual sales growth in the domestic market is more than 20%.
In terms of export sales, since the second half of 2015, based on feedback from major domestic export companies, major foreign buyers, and raw material suppliers, comprehensive analysis shows that the international market has emerged from the relative stagnation of the previous two years and has shown greater growth. By the first half of 2016, the overall annual growth rate is expected to be around 30% (the export year is a sales year from the second half of 2015 to the first half of 2016). The total export volume of PE-based plastic-wood composite materials in this marketing year is about 400,000 tons. It is expected that the volume of foreign orders from 2016 to 2017 will still maintain an annual growth rate of about 30%.
2. Industry scale
So far, there are about 200 domestic manufacturers of PE-based plastic-wood composite materials, of which about 25 were newly added in 2016. There are about 5 companies with an annual shipment of about 20,000 tons, and about 15 companies with an annual shipment of about 10,000 tons. The total production capacity of PE-based plastic-wood composite materials exceeds 1 million tons. Judging from the distribution of the number of PE-based plastic wood products companies, the Yangtze River Delta accounts for about 50%. In recent years, other regions have also developed rapidly, especially in the southwest and northwest regions, where there are more new product companies.
3. Product structure and new product development
In the past year, new product development has developed rapidly, and various product manufacturers have generally increased their efforts in new product development. It can be seen at the exhibition that quite a few companies have launched new products with their own characteristics. This is a relatively gratifying industry. Status.
In order to better improve the performance and appearance of the product, the application of surface coating engineering plastic technology and online embossing technology has promoted the production of the second generation of PE-based plastic-wood composite materials. With the R&D and vigorous promotion of some leading companies in the industry represented by MEMSIC, Sentai, Hualong, Helong, and Winbond, the second-generation PE-based plastic-wood composite materials will largely replace the first-generation products and make my country The plastic-wood composite materials have reached the international advanced level, and are on the same starting line with the United States and other countries.
Foaming and co-extrusion technology will be the future development direction of PE-based plastic-wood composites, which will solve the problem of lightweight products, greatly improve weather resistance, and reduce the cost of raw material formulations.
PVC quick-release wall panels have been launched since 2015, with low product prices and easy and quick installation
Simple and beautiful in appearance, this product has developed rapidly and will bring a revolution in the interior decoration industry.
Occupy the European market and open up emerging markets in Asia and South America
The plastic-wood industry is in the best period of development in history. In the future, my country's plastic-wood composite material manufacturers should vigorously explore emerging markets such as Asia and South America while occupying the European market.
