Polyamide Solar Panel Mid Clamp For Frameless Solar Panel Mounting

The polyamide solar panel mid clamp were extruded by higher performance, longer life than traditional aluminium fixtures, nonconductivity polyamide prevents the lossing of electric power, makes solar power be transferred more effectively.

    Jiangyin KAXITE TECHNOLOGY was the 1st one who successfully Extruded the polyamide 6.6 profiles applicated for solar power systems, instead of aluminium frames, with higher mechanical performance, longer life, lower cost, and better corrosion resistant. Now widely used in the solar photovoltaic industry all over the world.


  • The material of the fiberglass reinforced polyamide (PA66GF) was already widely applicated in the high end thermal break window and facade systems, acting as thermal break between aluminium profiles.

  • Density of polyamide is only 1.35 g/cm3, half of the density of aluminum, lighter and lower cost.

polyamide is lighter and cheaper than aluminum


  • Aluminum is a kind of highly activing metal, suffered from the corrosion from the environment. Polyamide is a kind of plastic which has excellent property of corrosion resistance, so has longer life than aluminum.

Polyamide (PA66GF) 13 years exposed to the environment, no corrosion happen. Aluminium profile 13 years exposed to the environment, oxidation reaction, acid corrosion reaction happened.


  • Most components applicated in electric systems are insulated, due to the limitation of technology and objective actors, aluminium frames were used in solar power systems, to protect the solar photovaltaic chips. But the electrical conductivity causes the electricity leakage.
electrical insulated and safer
discharge and leakage of electricity
Polyamide is electrically insulated material, no leakage, more safe. Aluminum causes the discharge and leakage of electricity.

  • 90% Recyclable after 20 years!

The performance of thermal barrier strips is in line with the Chinese standard GB/T 23615.1-2009 and the European Standard EN 14024:2004, for KAXITE series, the performance is rather higher than the standard value.

Details of related standard:

  • GB/T 23615.1-2009 Accessorial material for architectural aluminum alloy profiles -- Part 1: Thermal barrier strip of polyamide
  • EN 14024-2004 Metal profiles with thermal barrier -- Mechanical performance Requirement, proof and tests for assessment
  • YS/T 437-2008 Aluminium profiles moment of inertia calculation methods and computing software requirements
  • JG/T 174-2005 Thermal barrier strips for construction industry
  • GB 5237.6 -2012 Wrought aluminium alloy extruded profiles for architecture -- Part 6: Thermal barrier profiles
  • GB/T 8478-2008 Aluminium windows and doors
  • GB/T 8484-2008 Graduation and test for thermal insulating properties of doors and windows
  • JG 175-2011 Insulating aluminum alloy profiles with thermal barrier for buildings
  • NFPA 285 Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components
  • UL 94 V-0 The Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing

In 2015, we became the leader of the Chinese National Standard Committee (for revising of GB/T 23615.1-2009) .


For quality, the most important thing is to control the performance of the raw materials, as we have to ensure the expensive but indispensable additives  (e.x. Antioxidants & Anti-aging agents) were contained in the mixture. We have our own capacity of granulation for PA66 GF25 and many other kinds of plastic granules. We're the only one who used the technology of Vacuum Drying for the polyamide, which could highly improve the natural performance of the nylon granules.

We have series of brands, corresponding to different raw materials. For domestic series, they will be the domestic new PA66 and short chopped fiberglass, for KAXITE series, they will be the imported Dupond PA66 and short chopped fiberglass, which has rather better performance than the standard required.


Mostly we could finish the development of new products in 15 days.

The hardest thing is not thinking, but realizing. Most customers were upset that nobody could develop the shapes that they designed, some counterparts even came and looking for help to our workshop. We developing and cutting new dies for our customer, of course we never failed to develop any shape for our customers. 


    We have more than 40 extruders, production capacity of 550,000 meters per day. For common specifications, they‘re ready in stock, if customized, mostly the production could be finished in 7 days.


  For all specifications/shapes, they could be packaged in linear, the length will be 3.15 meters, or customized.
  Standard wooden cases for export.
