供應美國DuPont Rynite 545 BK504 PET材料介紹：

Rynite 545 BK504 is a 45% glass reinforced modified polyethylene terephthalate with good strength and stiffness, excellent dimensional stability and creep resistance.

杜邦PET材料特性：

When you’re looking for the ultimate combination of stiffness,

temperature performance, maximum dimensional stability, and

a high gloss finish, RYNITE  PET is the mostcost-effective answer.

It unites the best properties of reinforced polyethylene terephthalate

（PET） with easier processability to produce high performance

parts that can be moulded conventionally.

RYNITE  is the only PET-based polyester system with the virtue of

rapid crystallization. It also has a 20°C heat deflection advantage

over PBT. It can be processed over a broad temperature range.

And, because of its low water absorption, parts in RYNITE  PET

maintain their properties and dimensional stability. This makes it

a prime candidate for the replacement of die-cast metals and thermosets

in many demanding applications where stiffness, critical

tolerances and exterior finish are key requirements. The outstanding

flow characteristics of RYNITE  PET allow it to fillcomplex, thinwalled

moulds with less injection pressure than is needed with

other resins. This is a particularly important advantage with miniature

parts.

RYNITE FR530L, widely used inthe electrical and electronic component

industries, has a UL temperature index of +155°C, among

the highest of allthermoplastic polyesters.

杜邦PET材料應用：

1. This induction hob from BSH Balay is made of RYNITE, which was chosen for its dimensionalstability, stiffness and good mouldability. The RYNITE FR531 NC used by Balay was specially developedto support temperatures of up to 200°C.

2. RYNITE 545 was chosen for theconnector housing of this Bosch alternator because of the good combination ofmechanical properties it offers. In addition it has good thermal and

chemical resistance. It also permits high productivity in multi-cavitymoulds.

3. This encapsulated oscillating pump for carpet cleaners employs twodifferent

grades of RYNITE: FR530 and HP415. TheClass F homologation of these grades permit the use of this pump for export tothe USA. The possibility to laser print RYNITE  avoids the

utilisation of more polluting solventbased marking systems.

4. The recent range of irons launched by Braun is using a custom coloured,heat stabilised RYNITE PET for the iron skirt. RYNITE  gives higher productivity at lower total cost compared tothe thermoset which was used previously.

5. An earlier die-cast metal motor with fan （left）, and the re-designedunit in RYNITE （right）. The switchfrom metal to plastics meant simpler manufacturing, weight reduction, fewercomponents and lower assembly costs, reduced stock inventory and improved performancefor a range of vacuum cleaners from Electrolux.

6. Rear windshield wiper arms for cars like the Fiat “Punto" are made outof a RYNITE  grade which is specifically developed for severeweathering conditions. Mechanical properties

like creep resistance, as well as superior surface appearance, are ofmajor importance in this application.
