Description

W5B is a graft polymer containing glycidyl ester functional group, polyolefin elastomer as matrix material, high reactivity and low residue.

Performance comparison of W5B and imported polyester tougheners in PBT toughening

Physical index	Unit	Testing method	85%PBT+15%W5B	Add 15% imported polyester toughener
Tensile Strength	Mpa	D-638	38	38
stretch rate	%	D-638	60	67
Bending strength	Mpa	D-790	59	57
Flexural modulus	Mpa	D-790	1447	1397
Izod notched impact strength	J/M	D-256	540	550
Melt Index（235℃/2.16kg）	g/10min	D-1238	10.44	9.82

It can be seen from the above table that the super toughening effect achieved by adding 15% W5B in the PBT toughening system is close to that of imported polyester toughening agents.

Typical data of W5B in PBT fiber

Physical index	Unit	Testing method	70%PBT+30%GF	65%PBT+5%W5B+30%GF
Tensile Strength	Mpa	D-638	120	100
Bending strength	Mpa	D-790	170	160
Izod notched impact strength	J/M	D-256	90	150

It can be seen from the above table that adding 5% W5B can improve the notched impact strength and preserve other properties in the PBT fiber-added system. It shows that W5B has superior processing performance in the PBT fiber-added system and can help the glass fiber to disperse uniformly.

Typical Data of W5B in PBT Flame Retardant Reinforcement

Physical index	Unit	Testing method	56%+P1B4T%+3F0R%GF	52%PBT++41%4%WF5RB+30%GF
Tensile Strength	Mpa	D-638	110	107
Bending strength	Mpa	D-790	165	160
Izod notched impact strength	J/M	D-256	65	150
Residual rate	%	/	30.03	30.89
1/16 flame retardant	Grade	UL-94	HB	V0

It can be seen from the above table that adding 4% W5B in the PBT flame retardant reinforcement system can improve the notched impact strength and preserve other properties well. It shows that W5B has superior processing performance in PBT flame retardant reinforcement system and can help glass fiber and flame retardant to disperse uniformly.
