Class0 rubber is a new focus of the insulation material industry. How is it different from rubber and plastic in our cognition? What are the advantages of rubber and plastic compared with the familiar ones?

First, rubber and plastic insulation material "history"

The origin of rubber insulation materials can be traced back to the early 20th century, the initial development is limited by the level of technology and production costs. With the rapid development of industrialization, people's demand for thermal insulation materials and technological progress have promoted the development and application of rubber and plastics.

Driven by scientific and technological progress and production process optimization, rubber and plastics began to be popularized in building energy conservation in the late 20th century. For example, Denmark used rubber and plastics in 1972, but in 1985, the heating area increased by 30%, but the heating energy consumption decreased by 3.18 million tons of standard coal. People have seen significant social and economic benefits from rubber and plastics.

Today, the production technology of rubber and plastic has been very mature and efficient, and it is applied in various forms such as plate and pipe in the insulation and insulation of pipes, tanks and equipment in the fields of construction, chemical industry and metallurgy.

Today's building safety is getting higher and higher, and the code also makes it clear that outdoor buildings with a height exceeding a certain value or places with a high risk factor need to use materials with higher fire rating to avoid the occurrence of fire and weaken the damage caused by accidents.

In order to meet the requirements of high safety standards and high performance standards, Class0 rubber and plastics was born in the industry.

Two, the three differences between Class0 rubber and ordinary rubber and plastic

Fire performance: Compared with ordinary rubber and plastic, Class0 rubber and plastic has better fire performance, passed the British BS Class0, the United States FM APPROVED certification, in line with the national standard GB8624 flame retardant B1 requirements. Ordinary rubber has a certain fire performance, but does not have the strict fire standards of Class0 rubber.

After the British BS476-7 flame surface spread test and the British BS476-6 flame spread index test, the flame spread degree is lower, and the flame spread index is smaller, which is the superior fire performance of Class0 rubber and plastic compared with common rubber.

Wet resistance factor: Class0 rubber has a high wet resistance factor, which can effectively prevent water penetration and maintain the lasting stability of adiabatic performance. Under normal circumstances, ordinary rubber and plastic will enhance the waterproof ability through a protective layer such as aluminum foil veneer, which is more common in outdoor exposure scenarios.

Insulation performance: Class0 rubber has durable and stable thermal conductivity and uniform and fine cell structure, high foam closure rate and stronger insulation performance. Widely used in high standard requirements of central air conditioning, split air conditioning, construction, medicine, chemical, electrical appliances and other types of pipe and equipment insulation and insulation. The thermal insulation performance of ordinary rubber and plastic is usually suitable for the manufacture of rubber tubes, plastics and sports equipment and other scenarios with low thermal insulation requirements.

Class0 rubber is one of the highest levels of safety and reliability in the use of rubber and plastic insulation materials recognized by developed countries, and is now gradually used in scenes with higher fire performance and fire protection standards, such as hospitals, schools, high-rise buildings; Or it is the thermal insulation of reactors, storage tanks and other equipment in the industrial field to prevent heat loss and cold energy loss.

Uetersen rubber and plastic insulation materials, to meet the needs of a variety of scenarios, not only with a variety of non-combustible grade of conventional rubber and plastic insulation materials, but also with the development and production of Class0 grade rubber and plastic technical capabilities; At present, Uetersen Rubber and Plastic has been used in Luzhou high-speed railway Station, Zigong East Railway Station supporting facilities project, Sichuan Mianyang Changhong intelligent Manufacturing Industrial Park and other projects.
