The Difference Between Bitumen Bottom And PVC Bottom Of Square Carpet

Generally, in public areas such as offices, people choose to lay square carpets. However, the bottom of square carpets can be divided into PVC and asphalt bottoms. From the surface of the carpet, it is difficult to distinguish between these two types of carpets. What is the difference between PVC square carpets and asphalt square carpets? Below, UNIJOY will answer the difference between PVC square carpets and asphalt square carpets.

What is an bitumen square carpet?

Asphalt square carpet, which is backed with asphalt. Petroleum asphalt is a product in the process of crude oil processing. Asphalt has a wide range of sources, and secondly, asphalt can be recycled and reused. One disadvantage of asphalt carpets is that they cannot be removed and replaced after being laid on the ground for too long. However, due to their relatively cheaper price compared to PVC square flooring, many companies are still willing to use them.

What is a PVC square carpet?

PVC square carpet is a carpet produced using polyvinyl chloride resin material as the bottom back of the square carpet. It is mainly made of polyvinyl chloride and its copolymer resin as the main raw material, and added with fillers, plasticizers, stabilizers, coloring agents and other auxiliary materials. It is made on a continuous substrate in the form of sheets and is uniformly mixed, coated, or molded through rolling and extrusion processes. It can be used instead of pure wool carpets and synthetic fiber carpets.

Introduction to the differences between PVC square carpets and asphalt square carpets

Aesthetics

PVC carpets are relatively flat, with straight edges, seamless, and not easy to remove threads and hair, making them aesthetically pleasing.

Difficulty in dismantling

The removal of asphalt with universal adhesive is difficult, especially for ceramic tiles and terrazzo floors.

PVC bottom has better dimensional stability

In the experiment of testing dimensional stability, the PVC bottom carpet was heated in a microwave oven at 60 degrees Celsius for 24 hours and immersed in water at 60 degrees Celsius for 24 hours. The results showed that the size of the PVC bottom carpet was only 0.5% smaller than the original factory specifications.

PVC bottom has better load-bearing capacity

The PVC base has a more precise structure, providing better support for some bulky furniture, preventing the carpet from being damaged due to its heavy load point, while asphalt floor is more fragile. When heavy objects are placed on it, it will leave an irreparable mark on the felt, making the surface of the felt not smooth.

PVC square carpets only produce toxic gases at high temperatures

PVC bottom only produces toxic gases when the high temperature reaches 240 degrees Celsius, and in fact, humans cannot survive in this high temperature. People usually die from inhaling thick smoke and high temperatures before the toxic gas is produced. On the contrary, the asphalt base has begun to produce a large amount of black smoke at 140 degrees Celsius, which affects the rescue work of firefighters.
