Wuhan Yuanfa Plastic Products Co., Ltd. has been firstly certified as “Industry authorized Enterprise” by China Construction Metal Structure Association of Aluminum Curtain Wall Commission and the product PA66GF25 thermal barrier strip becomes “the recommended products cited” in the industry.
Our company undertook and drafted GB-T23615.1 National Standard Accessorial material for architectural aluminum alloy profiles-Part I: Thermal barrier strip of polyamide.
PA66GF25 thermal barrier strip - C Shape strips
Service Advantages
Design and development of new-model thermal barrier strip
Shortest supply period; normal types available;
Sizes to be determined subject to the requirements of customers (500m/pic)
Technical Support
To provide the matching and the most advanced production line of thermal barrier materials and the relevant services.
Product Features
- The working temperature of the thermal insulation strip is 220°C, Melting Point reaches to 246°C. This enables coating process after assembly of composite profiles;
- High mechanical strength, able to connect with metal hardware fittings when bearing draw and shear stress;
- Excellent product tolerance of less than 0.1mm, ensuring air and water tightness and overall composite profile dimensions;
- High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage;
- The thermal expansion coefficient of PA66GF25 is similar to aluminum thus ensures that product does not affect the integrity of the thermally insulated aluminum profiles;
- Precisely dimension ensures the lifespan of aluminum extrusion tools, no danger of bending cracks during rolling, very good knurling effect at the hammer head and easy to assemble.
- Energy conservation and environment-friendly products; Management Certification: ISO 9001:2008.
Product Performance
GB/T 23615.1-2009 Accessorial for architectural aluminum alloy profiles
Part 1: Thermal barrier strip of polyamide
Based on the Chinese standard GB/T 23615.1-2009 Thermal barrier strip
Strips Date Sheet Insulating Strips of PA66GF25
1) Sample water content less than 0.2% by weight.
2) Norm laboratory condition: (23±2)% and (50±10)% relative humidity
3) The specifications marked with "a" only applies to I-shape strip otherwise, the specifications, concluded between supplier and buyer through consultation, shall be written in contract or purchase order.
Advantages of Thermal Insulation System
- Effectively increased thermal in the system property insulation;
- Reduces condensation on the window;
- Sound insulated;
- Improve comfort and living condition;
- Possible double color coatings provide better aesthetic effect.
Packing specification
- The products, with a length of 6m for a piece, 100 pieces for a bundle, are packed with transparent plastic film.
- As required by the customers, 10000 meters in one package, with 500m/pic each.
Storage Conditions
It is suggested that the product be stored in the ventilated and dry environment, horizontally placed, paying attention to waterproof, keeping away from the heat source, avoiding heavy pressure and the contact with acid, alkali as well as organic solvent.
Methods of distinguishing between the authentic and fake thermal barrier strips
In view of sophisticated international thermal barrier strip market, some adopt common plastic of non-structure materials such as ABS, PP, even PVC to replace the engineering plastic to make the so-called thermal barrier strip. One method of easily distinguishing between the real and fake thermal barrier strip is hereby provided:
Put the thermal barrier strips make of PVC, ABS, PP, PA6 (nylon6), PA66 and other materials into the oven and heat up. Those Softening and degradation occur around 90°C are PVC materials; those around 160°C are PP materials and ABS materials, those around 210°C are PA6 materials, however when the temperature of the thermal barrier strip made of PA66 materials if under 240°C, there is no obvious change on the appearance.
In short, the quality of thermal barrier strip is the one without any obvious change on the appearance under the high temperature between 210°C - 240°C.
Each YUANFA strip comes with a laser marking
