Removing Stains from Walls The Magic Eraser is not scared of your scuffs and stains. Marla Mock, president of Molly Maid, says that a damp Magic Eraser can make scuff marks on your walls disappear ...
Hydroperoxide decomposition occurs when metal and metal ions within the plastic material lead to the deterioration of the object [13] Plasticizer migration occurs when additive chemicals intended to keep a plastic resin soft and pliable gradually move to the surface or are shed from an object. The loss of these chemicals causes the plastic to ...
Retrobright (stylized as retr0bright or Retrobrite [1]) is a hydrogen peroxide-based process for removing yellowing from ABS plastics. Yellowing in ABS plastic occurs when it is exposed to UV light or excessive heat, which causes photo-oxidation of polymers that breaks polymer chains and causes the plastic to yellow and become brittle.
The sap is processed to remove impurities. [5] The production of lacquerware involves a process of applying a ground layer, [ 6 ] oftentimes lacquer mixed with other substances such as clay or a layer of fabric , followed by many very thin layers of processed lacquer to a substrate, typically wood , and allowing them to dry completely, [ 6 ...

Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid form. Tar is sometimes used interchangeably with pitch, but generally refers to a more liquid substance derived from coal production, including coal tar, or from plants, as in pine tar. [2]
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.
