PVC foam board generally refers to Chevron board, which can also be called Andy board. This kind of board is made of polyvinyl chloride as the main raw material, added with foaming agent, flame retardant and anti-aging agent, and extruded with special equipment.
It is widely used in construction, vehicle and ship manufacturing, furniture, decoration, decoration, advertising production, exhibition signs, city appearance and environmental protection, tourism and other industries. The advertising characters are made by an engraving machine or by hand, and the thickness is generally 0.3-2 cm. There are two common production methods: one is crust foaming, with a hard skin on the surface, smooth and flat; the other is free foaming, with no crust on the surface, and the surface is finely uneven (pitted surface). Common colors are white and black.
Chevron board is comparable to wood, and it can be sawn, planed, nailed, glued, and has special functions such as no deformation, no cracking, and no need to paint (with a variety of colors); while low-foaming boards can be welded, It is printed with ink and can also be machined by sawing, drilling, milling and other methods.
