Product Text
Common features of Crastin® thermoplastic polyester resin include mechanical and physical properties such as stiffness and toughness, heat resistance, friction and wear resistance, excellent surface finishes and good colourability. Crastin® thermoplastic polyester resin has excellent electrical insulation characteristics and high arc-resistant grades are available. Many flame retardant grades have UL recognition (class V-0). Crastin® thermoplastic polyester resin typically has high chemical and heat ageing resistance.
 
The good melt stability of Crastin® thermoplastic polyester resin normally enables the recycling of properly handled production waste.
If recycling is not possible, DuPont recommends, as the preferred option, incineration with energy recovery (-24 kJ/g of base polymer) in appropriately equipped installations. For disposal, local regulations have to be observed.
 
Crastin® thermoplastic polyester resin typically is used in demanding applications in the electronics, electrical, automotive, mechanical engineering, chemical, domestic appliances and sporting goods industry.
 
Crastin® HR5315HFS is a 15% glass reinforced PBT with high flow, moderately toughened, hydrolysis resistant (HR) polybutylene terephtalate for injection moulding.
 
Injection molding
PREPROCESSING
Drying recommended = Yes
Drying temperature = 110-130℃
Drying time, dehumidified dryer = 2-4 h
Processing moisture content = <0.04 %
 
PROCESSING
Melt temperature optimum = 250℃
Melt temperature range = 240-260℃
Mold temperature optimum = 80℃
Mold temperature range = 30-130℃
 
Use of hot-runners is possible with Crastin® HR resins. 
However we do not recommend temperature settings above 270℃ and residence times at 265℃ should be below 10 minutes.
In case of longer residence times using hot-runners, for example after a shut-down, the complete system must be purged with glass reinforced Crastin® (type SK602/605) before starting up again.
For successful processing of Crastin® HR with hot-runners, care should be taken to maintain a uniform temperature, avoid hot-spots and long residence times.
