The chemical composition of sintra board is polyvinyl chloride, also known as PVC foam board. PVC board is made of PVC as raw materials, a kind of plate with a honeycomb mesh structure. Many people often confuse the two concepts and think that PVC board is a sintra board, in fact, they are not the same concept.
The type of sintra board is divided into crust type sintra board and free type sintra board according to its different production process, their hardness is different, and the surface effect is different. Crusted sheaf surface is very hard, it is difficult to produce scratches, generally used in construction or cabinet processing; The surface of the freestyle sintra board will have a convex and convex pockmark effect, and the hardness is low, and it is generally used in advertising display boards, engraving or screen printing.
1. Classification OF PVC Sheet
PVC boards are divided into PVC skin foam boards, PVC free foam boards and PVC co-extrusion boards according to the manufacturing process.
1. Skin Foam Board (also known as sintra board or Andy board) have a hard skin on the surface (single-sided/double-sided) and are harder and less prone to scratches. The cutting surface has a slightly sandy texture. The price is slightly higher. It is mainly used for carving crafts. The board is hard and the carving has no burrs. It can be carved into various shapes.
2. PVC Free Foam Board (also a type of sintra board) have a surface hardness of general level, with fine and dense honeycomb texture. It may leave scratches. The price is slightly lower. The product is mainly used for advertising pasting pictures, printing and other purposes.
3. PVC Co-extrusion Board are different from ordinary foam boards in that the adhesive film used in the latter is glued with glue at room temperature, and will peel off within a short time (1-2 years). The former uses a vacuum laminating machine and is glued at a higher temperature, so it is less likely to peel off. It adopts the advanced “two extruders co-extrusion” production process, with no foaming on the surface layer, smooth surface and high hardness, mainly used for craft-level carving products, such as various shoe cabinets, shoe racks, display stands, screens and partitions.
2. PVC Board Types
According to its appearance and state, PVC boards can be classified into the following types:
1. PVC Foam Board, also known as sintra board, has obvious anti-corrosion and moisture-proof properties, and is easy to be processed by hot forming and bending. It is widely used in furniture, kitchen cabinets, exhibition boards, indoor and outdoor decoration, product packaging, etc.
2. PVC Rigid Sheet has the characteristics of corrosion resistance and insulation, and can be processed into sulfur tank, medical needle rack, product template, decorative board, exhaust pipe and other products through secondary processing. It is a good material for chemical, building materials and other industrial fields.
3. Anti-static PVC Board, with an appearance of smoke color, milky white or gray, is usually used to make equipment covers and dust-free boxes.
4. PVC Transparent Sheet, made of imported raw materials, is a type of plastic sheet. It has many varieties of colors, including white, tea color, coffee color, etc. PVC transparent board has the advantages of high strength, high transparency, and no toxicity, and is usually used for processing equipment covers and drinking water troughs.
5. PVC Soft Board belongs to the roll material, with a glossy surface and various colors such as brown, white, and gray to choose from. Due to its characteristics of wear resistance, corrosion resistance, tear resistance, and weldability, it is widely used. It is usually used as the lining of chemical and electrolysis tanks, insulation board, interior of trains and cars, etc.
6. PVC Plastic Board is a thermoformed plastic widely used in chemical, environmental protection equipment, medicine, electronics or decoration industries.
There are also many other types of PVC Sheet, such as Celuka PVC Board, PVC Co-extrusion Board, PVC Building Formwork, PVC UV Sheet, PVC Floor,WPC Board,PVC Marble Sheet, etc.
3. Juxin Plastic PVC BOARD
The following characteristics are possessed by the PVC sheets produced by PVC manufacturers—Juxin Plastic Group.
1. Strong resistance to corrosion: suitable for the manufacture of anti-corrosion equipment in the chemical industry;
2. Easy to process, good plasticity, no pollution during hot bending, no toxic volatile ultraviolet radiation;
3. Weather resistance, able to withstand temperatures ranging from -40 to 60 degrees Celsius;
4. Good flame retardant performance, extinguished upon leaving the flame;
5. Low water absorption, waterproof and moisture-proof, easy to adhere to, easy to paint; 6. Easy to install and low maintenance cost.
The article lists all the categories of PVC boards, and it is not difficult to find that there are many types of PVC. PVC boards are a type of board that contains PVC, while PVC foam board, also known as sintra foam board, includes skin-type sintra foam board and free-style sintra foam board. Sintra foam board and PVC boards are subordinate and dependent relationships, rather than the same concept. Sintra foam board is the subordinate, and PVC boards are the main.
