Product Description

Company Profile

The rockwool production line of Anhui Liluan Technology Co., Ltd. was established in 2009. It is located in Gushu Industrial Park, Dangtu County, a beautiful town in the north of Chang Jiang River, covering an area of more than 100 acres. The registered capital are 60 million yuan, and the company's total capital is about 80 million yuan. It has the most advanced automatic rockwool production line in China. The annual production capacity is more than 50K tons of high-quality rockwool boards.

Product Description

Rock wool strips are mainly used in two areas: exterior wall insulation rock wool strips and metal-faced sandwich rock wool strips. Liluan external wall insulation rock wool tape (HD series) is a fireproof insulation material, mainly used in the external wall insulation thin plastering system and dry hanging curtain wall insulation system for new construction, expansion and renovation of existing buildings, or used in conjunction with insulation materials such as EPS, XPS and PU whose combustion performance does not reach Class A, to improve the fireproof performance of the building's external wall insulation system. This product can also be used for fire prevention, insulation, and sound absorption of garage roofs or indoor ceilings. Metal faced sandwich rock wool strips are widely used in sandwich rock wool core materials such as mechanism purification boards, ordinary composite boards, and decorative integrated boards, playing a role in fire prevention, insulation, sound absorption, and noise reduction.

Advantages
1.Rockwool is made of natural rock and is a Class A non-combustible fireproof material. Its melting temperature is over 1000ºC,
   which can effectively slow down the spread of fire.
2.The thermal conductivity is low and the thermal insulation effect is significant.
3.Greatly reducing the reflection and propagation of sound waves and providing a beneficial environment without interference for       work and life.
4.The open porous fiber structure makes rockwool have excellent air permeability and moisture-drying function, which allows
   water vapor to pass freely, effectively reducing condensation and building mildew.
5.The rock wool for external wall insulation, high-strength rock wool board for roofs and composite board with rock wool have high
   tensile strength and compression strength, which can effectively resist the alternating effects of positive and negative wind
   pressures and have strong impact resistance.
6.Rock wool is frost-resistant, freeze-thaw resistant, and UV-resistant. It does not produce thermal expansion andcontraction due
   to temperature differences in the four seasons. It can be used in extreme climates without being affected by other combined
   materials. 
7.Water-repellent and moisture proof.
8.The energy saved by rock wool in use is more than 100 times the energy consumed in its production, transportation and
    recycling.
9.Safe and environmental protection.
10.Easy to carry and cut. It can be completed with a scissors.
