Plastic Weathering Fundamentals - SlideShare Apr 23, 2014 ... Relative Weathering Resistance of Plastic Materials Due to diferences in their chemical composition, various polymers respond diferently to the efects of UV radiation, resulting in very diferent weatherability characteristics. As shown below, some materials such as acrylics and fuoropolymers are inherently...

Accelerated Weathering Testing for Plastics and Polymers - Intertek Intertek provides accelerated weathering testing of polymer and plastic materials and products through a plethora of different tests. Our experts ... The polymer materials or products will be exposed under defined conditions to heat, UV, and other stress to determine its critical properties before and after exposure. Materials...

Plastic materials and durability: weathering testing - AIMPLAS Jul 22, 2016 ... Given its nature, during weathering testing and ageing test, the movement of molecular chains or their breaking up affects the properties of plastics, almost always to make them worse. Let's see how some weathering agents affect: Cool: low temperatures, below material's glass transition temperature,...

Toxicity of leachate from weathering plastics: An exploratory ... Between 60% and 80% of all marine litter is plastic. Leachate from plastics has previously been shown to cause acute toxicity in the freshwater species Daphnia magna. Here, we present an initial screening of the marine environmental hazard properties of leachates from weathering plastics to the marine harpacticoid...

Factors of polymer weathering - Wikipedia The aging of natural and artificial polymeric materials is a natural phenomenon in metals, glass, minerals and other inorganic materials. The main environmental parameters influencing the degradation of polymeric materials is daylight combined with the effects of temperature, moisture and oxygen. These act as the main...

Weathering Resistance - Dietzel Univolt Long term exposure to sunlight, particularly to UV radiation, results in breaking down of polymer chains, thus impeding phy- sical properties, changing of colour and chalking of surfaces. In the worst case plastic products become brittle and even disin- tegrate after short time. To protect cable management systems against the...
