Product Description

DIMEX PA66GF25 Series Heat Insulation Strips

Heat insulation strips' introduction:
Heat insulation strip is the core component of the thermal barrier aluminum profiles. The quality of heat insulation strips not only determines the heat insulation effect of aluminum windows/doors, but also determines the application experience of windows/doors.

Heat insulation strips features:
The heat insulation strips are composed of polyamide (PA66) and 25% glass fiber (GF). It's color is black.It is mainly used in the high-end aluminum alloy windows&doors, framed curtain wall and high-end bridge-cutoff aluminum with excellent performances such as strong thermal insulation, high hardness, uninflammability, energy conversation and environmental protection. Its application plays a decisive role in wind load resistance, water tightness and air tightness of the windows&doors, which is also the theme of Nylon heat insulation strips.

The thermal expansion coefficient of thermal expansion is similar to that of the aluminum profile (2.5-3*10-5/K), which ensures the thermal insulation strips and aluminum materials will be tightly combined for a long time not to fall off under sunlight exposure and freezing conditions.

Scientific, rigorous , precise and unique formula and special thermal stabilizer ensure the excellent qualities of DIMEX thermal insulation strips.

The high precision, low tolerance and smooth surface ensure the air tightness and water tightness of windows.

DIMEX thermal insulation strips have the outstanding properties of excellent machining performance, aging resistance, strong chemical corrosion resistance and UV resistance.

What is PA66GF25?
PA66 refers to its material is mainly polyamide 66(commonly known as nylon 66 or PA66), while GF25 refers to the heat insulation strip added with reinforcement 25% glass fiber (GF for short).  The toughness and strength of heat insulation strip is much better after adding 25% glass fiber,and the tensile strength can easily reach more than 80 MPa.

The thermal insulation strips made of PA have a certain water absorption
The rate and amount of water absorption depend on the following factors:
1)Ambient humidity;
2) Ambient temperature;
3) Storage time.
In summer, the temperature and humidity of the warehouse are relatively high, and the insulation strips will absorb more water than other seasons, so it should be stored for a short time. When stored in a dry environment, the relative humidity is low,but if the storage time is too long and the moisture content of the insulation strip exceeds 2%, which will lead to the expansion of the insulation strips and thus causing difficulty putting them into the slot, or bubbles in the spraying process. Therefore, it is recommended that they should be stored indoors at a temperature of 15-23ºC. At the same time , the storage location should prevent soaking.
