Description

W5D is a graft polymer containing glycidyl ester functional groups, olefin copolymer as a matrix material, high reactivity.W5D polyester compatibilizer is POE-based material by introducing strong polar reactive group GMA (glycidyl methacrylate), so that the material has high polarity and reactivity, which can be used for flame retardant, reinforcement, enhancement The modification of polyester materials such as toughness, filling, etc. can effectively improve the compatibility of composite materials and the dispersion of fillers, and improve product performance. It can also be used as a compatibilizer for ABS/PC, PBT/PC and other alloys. This compatibilizer has obvious advantages for PBT flame retardant and fiber addition.

Typical data of W5D in PBT plus fiber

Physical property index	Unit	Test method	70%PBT+30%GF	65%PBT+5%W5D+30%GF
Tensile strength	Mpa	D-638	120	100
Flexural strength	Mpa	D-790	170	160
Lzod notched impact strength	J/M	D-256	90	120

From the above table, adding 5% W5D in the PBT fiber system can improve the notched impact strength and preserve other properties well. The results show that W5D has superior processability and high fluidity in the PBT fiber system can help the glass fiber to disperse better.

Typical data of W5D in flame retardant reinforcement of PBT

Physical property index	unit	Test method	56%PBT+30%GF+14%FR	52%PBT++41%4%WF5RD+30%GF
Tensile strength	Mpa	D-638	110	110
Flexural strength	Mpa	D-790	165	170
Lzod notched impact strength	J/M	D-256	65	120
Residual rate	%	/	30.03	30.23
1/16 fire resistant	level	UL-94	HB	V0

Note: PBT Taiwan Changchun 1100 -211 M GF Jushi 988A Antimony trioxide Brominated epoxy

It can be seen from the above table that the addition of 4% W5D in the PBT flame retardant reinforcement system can improve the notched impact strength and preserve other properties well. It shows that W5D has superior processing performance in PBT flame retardant reinforcement system and high fluidity can help glass fiber to disperse better.

Typical data of W5D in PC+PBT alloy

Test raw materials: PBT (Changchun 1100N), PC (Teijin 1250Y); Test equipment: 35 type twin-screw extruder granulator

Performance	Unit	PC+25%PBT	PC+20%PBT+5%W5D
Tensile strength	MPa	Poor compatibility, layering	55
Flexural strength	MPa	Poor compatibility, layering	85
Lzod notched impact strength	J/M	Poor compatibility, layering	650
