Polymeric organic phosphorus compounds are high relative molecular mass of condensed phosphate, now is widely used for resorcinol condensed phosphate and bisphenol A diphenyl phosphate.
Flame retardant PC/ABS alloy and ABS content, reach UL94V - PC/ABS alloy
Level 0 the adding amount of RDP required increases with the increase of ABS plastic injection processing material content.
Bisphenol A type of condensed phosphate good thermal stability, processing does not cause the rise of viscosity of alloy, and can be recycled.
to flame retardant PC/ABS modified, is meet the requirement of some application field of flame retardant materials. The flame retardant PC/ABS alloy with phosphorus are coated red phosphorus and organic phosphorus compounds. High phosphorus content of red phosphorus, is excellent flame retardancy of phosphorus-containing flame retardants. Darker red phosphorus, inappropriate light products of flame retardant. Organophosphate compounds have low molecular organic phosphorus compounds, and two kinds of polymeric organic phosphorus compounds.
the bibulous rate of PC/ABS alloy is smaller than a PC, boiling water resistance was significantly more than the PC, after 1000 h boiling water processing, the impact strength of PC/ABS alloy remained 50%, while PC is only 20% contained. PC/ABS cost is lower than PC, high performance/price, ivory color and luster is good, not transparent. To enhance, flame retardant PC/ABS alloy, electroplating, etc of modification, can further improve the performance of the alloy and alloy new functions.
PC/ABS alloy with glass fiber, can raise the bending strength of alloy, the tensile strength and thermal deformation temperature, with the increase of glass fiber content, the tensile strength and bending strength increase, the notched impact strength and elongation at break decreased. Due to glass fiber reinforced PC/ABS alloy than the PC/ABS alloy has higher mechanical properties, thus it can be better used as a structural material. Have certain flame retardant PC itself, after joining the ABS, flame retardancy is slightly reduced.
PC/ABS alloy processing fluidity of pressure sensitivity than pure PC, pressure, the alloy melt index increases accordingly. The pressure of pure PC melt index have little impact. Processing temperature effect on liquidity of PC/ABS alloy is bigger, temperature, melt index increased significantly. Therefore, through the method of higher pressure and temperature can improve the melt index of PC/ABS alloy, thus improve the processing fluidity, heating is more effective than increase pressure.
PC/ABS alloy, heat distortion temperature between PC and ABS, can be in 100 - Using deformation within 150 ℃ temperature range. The effects of a load on the thermal deformation temperature. PC/ABS alloy melt index is higher than the PC, and also has a high melt index in low temperature area. PC/ABS alloy greatly improved the processing fluidity of PC, forming large thin-walled injection molding processing parts. PC/ABS alloy molding shrinkage of small, differ with the PC is not big, can be used to make the products of the high dimension precision requirement.
low molecular organic phosphorus compounds represent varieties have triphenyl phosphate, the TPP phosphorus is 9. 5%, about 50 ℃ melting, relatively volatile. PC/ABS alloy with 13. 5% of the TPP, alloy UL94V - flame retardancy 0 level and UL945V level, increase the content of ABS or reduce the content of the TPP, reduce alloy flame retardancy. The TPP is suitable for the low content of ABS flame retardant PC/ABS alloy. TPP for PC/ABS have plasticizing effect, so the TPP heat distortion temperature of the flame retardant PC/ABS alloy.
