Automobile Grille Thermal Management System Low-voltage Apparatus

Introduction for components

Low-voltage Apparatus

Low-voltage Apparatus is an electrical device which DC voltage is less than 1500V and AC voltage is less than 1200V. It manually or automatically switches on and off circuits based on external signals and requirements to switch, control, protect, detect, transform, and adjust circuits or non-electrical objects.

Requirements for components

strength

heat resistance

high temperature creep resistance

insulation strength

high CTI

greenness and environmental protection

thermosetting replacement

metal replacement

Material selection for components

High performance halogen-free flame retardant material of JinYoung Polywork®High performance semi-aromatic polyamide material

JinYoung provide halogen-free flame retardant solutions including PBT, PC, PA6, PA66, PA1010, PPA and PPS for low-voltage electrical appliances, bringing high electrical safety and cost effectiveness to our customers.

JinYoung material solutions have:

Good processing performance——excellent fluidity, good molding appearance, low corrosion, low precipitation, low volatilization
Excellent heat aging performance——excellent RTI performance
Excellent electrical performance——excellent insulation aging properties under 150 ℃, good dielectric strength, high electrical life

JinYoung Polywork®high-performance semi-aromatic polyamide material is made by polycondensation reaction of diacid containing benzene ring and aliphatic/aromatic diamine. It has the advantages of ultra-high stiffness, low water absorption, excellent chemical resistance and high temperature creep resistance. It is applied in low-voltage electrical components such as lever, rotating shaft, locker, contact holder, tripping bar, cam and housing.

Polywork®high performance semi-aromatic polyamide material have：

Chemical resistance——resistance to fuel, alcohols, acids, chemicals, etc
Easy to processing——liquidity is good, suitable for thin wall design, low flash
Dimensional stability——low water absorption, high rigidity, dimension stability
High heat resistance——high melting point, good thermal stability
High temperature creep resistance——high glass transition temperature, high crystallinity, extremely low creep at high temperature
High mechanical performance——high strength, high modulus, with excellent toughness

High Tm/Tg, suitable to continue to work at high temperature
