Q14
What are blooming and bleeding?
A14
Blooming and bleeding refer to phenomena in which 無料オンライン カジノ and/or plasticizers in the polymer migrate to its surface. The discharge of these substances in the form of solid or liquid impairs the design aesthetics of the products. In general, blooming refers to the discharge of solid substances, whereas bleeding refers to the discharge of liquids.The cause is that the compatibility between the polymer and the additive is poor.
Corrective Measures
- 1
- Use 無料オンライン カジノ that have good compatibility with the polymer. For example, select an additive with a solubility parameter (SP value) close to that of the polymer.
- 2
- With respect to migration properties, select 無料オンライン カジノ that are suitable for the environment in which the plastic product will be used (particularly with regard to temperature). When polymers are used at high temperatures, or at relatively low temperatures, 無料オンライン カジノ need to be selected in accordance with the molecular weight and heat resistance etc. of the 無料オンライン カジノ.
Q15
What is fogging?
A15
Fogging refers to the phenomenon in which 無料オンライン カジノ volatilize from polymers, so that they adhere to and fog the glass or walls etc., impairing the design aesthetics of the product.
Corrective Measures
- 1
- Use high molecular weight 無料オンライン カジノ with low volatility.
- 2
- Select 無料オンライン カジノ that are suitable for the environment in which the products will be used. With regard to the light stabilization of molded articles used in relatively high temperature environments, such as materials for automobile interiors, 無料オンライン カジノ with higher molecular weight is better, as lower molecular weights 無料オンライン カジノ such as HALS are prone to be fogging. 無料オンライン カジノ which have optimal molecular weights and compatibility should be selected.
