Tianjin Ruifeng insulation strip is composed of 65% nylon (PA66) and 25% glass fiber (GF) insulation strip raw materials. The color is black. As the main insulation component, it is suitable for aluminum alloy doors and windows, framed curtain walls, and special It plays a decisive role in the three main performances of wind pressure resistance, water tightness and air tightness of doors and windows.
To
Product advantages are as follows:
1. Using cold extrusion technology, the glass fiber is uniformly distributed in multiple directions and has high strength. It can meet the design requirements and ensure the long-term stability of the insulated aluminum alloy doors and windows and the framed curtain wall.
2. The coefficient of linear expansion is close to that of the aluminum material to ensure that the heat insulation strip and the aluminum material are permanently and tightly combined under the sun exposure and severe cold freezing.
3. The processing temperature is as high as 235 degrees, which meets the technological operation of first piercing and spraying.
4. The dimensional accuracy is less than 0.05MM, and the high size is evenly processed by rolling and rolling, which also ensures the airtightness, watertightness and wind pressure resistance of the door and window curtain wall.
5. Excellent machining performance, can fasten hardware.
6. It has the functions of fire resistance, high temperature resistance, chemical corrosion resistance, anti-aging, anti-ultraviolet, etc., is more environmentally friendly and energy-saving, has a longer service life, and can be recycled.
7. Unique formula and special heat stabilizer ensure the excellent quality of "Jinruite" heat insulation strip.

The insulation strip made of polyamide is dry when it is first produced, but then it will gradually absorb moisture from the surrounding environment. The speed and amount of water absorption depend on the following factors:
To
A Ambient humidity B Ambient temperature C Storage time
To
In summer, the temperature of trousers is relatively high. If stored in a timely manner for a short period of time, the heat insulation strip will absorb more water than other seasons. Too high water content (2%) will affect the threading or produce blisters during the spraying process. A single bundle of strips may be distorted if they are removed on parole. If they are not straightened, they will be distorted, making it difficult to recover in a short time. In order to prevent distortion and bending deformation, it is necessary to ensure the support of the extended part of the insulation strip, and to shorten the pre-processed storage as much as possible.
