- Aging Testing
Aging testingis the process of simulating the conditions of the product in the actual useconditions of the product to carry out the corresponding conditions tostrengthen the experiment. The experiment is mainly for plastic materials, thecommon aging is mainly light aging, hygrothermal aging, hot air aging . Theproduct is used outdoors in the sun for a long period of time. To understandthe longevity of the product that can be used in the outdoors, it is necessaryto simulate the UV-ultraviolet aging experiment using solar ultraviolet light.Of course, the intensity of the experiment is much greater than that of theactual outdoor lighting, thereby shortening the test time. The short-term testcan be used to understand how many years after the product has been used.

In thesame way, if the product is used in a bathroom or other humid environment withhigh humidity, heat aging is required. If the product is used in theheat-dissipating position of the machine, hot air aging is required. Of course,according to the export of the product to different countries and regions,there will be corresponding testing standards.
Plastic/rubber products (including PP,PVC, natural rubber, etc.), especially plastic shells, plastic fasteners, etc.
Coating/adhesive products (industrialcoatings, architectural coatings), especially coatings for outdoor use.
Outdoor decorations (including outdoorlight boxes, outdoor plating parts, etc.) More testing scope should bedetermined according to specific test requirements
The breakdown of products that can betested for burn-in testing is as follows:
Plastic products aging test include:plastic particles, plastic wire, plastic rope, plastic tape, hose, hard tube,bellows, plastic sheet, plastic film, plastic switch, plastic doors andwindows, plastic rods, artificial leather, cables, foam materials, plasticsProfiles, car accessories and so on.
Rubber products aging tests include:hoses, seals, films, conveyor belts, seals, insulation jackets, tires, pads,hoses, conveyor belts, rubber, waterproof membranes, automotive accessories.
Coating adhesive aging tests include:anti-corrosion coating, waterproof coating, thermal insulation coating,high-temperature coating, conductive coating, potting sealant, stickers,hot-melt adhesives, adhesive and so on.
Metal salt spray test materials:steel, metal components, etc.
