摘要:
A retention clip for hardware may include a support surface having an aperture extending through the support surface. The support surface may surround an entire perimeter of the aperture. The clip may further include at least one anti-rotation surface extending from the support surface in a non-parallel direction, and a plurality of angled tabs extending from the support surface in non-parallel directions towards the aperture. At least a portion of each angled tab may be disposed directly below the aperture. The tabs may be elastic below a preset load placed on the tabs, and the tabs may deform and lose their elasticity above the preset load.

摘要:
Zinc is added to a halogen-containing plastic composition with or without a flame retardant additive to serve as a smoke suppressant during combustion of the plastic.
摘要:
Low density alkaline earth metal sulfate fillers are used at levels below 40 phr in polyvinyl chloride thermoplastic resin formulations to improve processibility of the resin formulation and produce a thermoplastic material having retention of elongation and penetration resistance superior to known high temperature PVC thermoplastic materials.
摘要:
Magnesium oxide and a zinc salt are reacted with one another to form a magnesium zinc complex salt which is added to a halogen-containing plastic composition to serve as a smoke and/or fire retardant during combustion of the plastic. This magnesium-zinc complex salt is normally added along with an antimony compound but may be used alone if desired.
