Neaz Ahmed, assistant manager for product application at Natpet, comments: "H03TF, with its enhanced dimensional stability
, is giving packaging customers an opportunity to reduce their cycle times and achieve better products with less wastage, for all-round productivity improvements.
The new material addresses the problem of maintaining dimensional stability
of high temperature materials: stiff, semi-crystalline high-temperature polymers such as PEEK or polyphenylene sulphide often warp during injection moulding, while the dimensionally stable amorphous thermoplastics such as polyether sulphone are usually more difficult to process.
Traditional aluminum castings lacked dimensional stability
and increased machining time, which led to higher costs.
Designed for thermal/electrical applications requiring high dimensional stability
, Pyropel HDT plastics are 25 to 30 percent less expensive than competing materials, while offering superior dimensional stability
, heat resistance, high strength and reliability.
Because they are lightweight, our carbon fiber rolls provide less deflection, reduce roll vibration, provide higher critical speeds as well as good dimensional stability
CLTE-XT is a micro dispersed ceramic PTFE composite utilizing a woven fiberglass reinforcement to provide the highest degree of dimensional stability
, critical in multi-layer designs.
The standard Terblend N includes in its attributes a pleasant feel, good acoustic properties and good mould surface replication while the polyamide element contributes dimensional stability
under heat and the good flow properties.
The new ViaMat paper delivers improvements in dimensional stability
and enables higher interconnect densities.
the high costs and lengthy processing requirements of imidized thermosets, and the poor creep resistance and poor dimensional stability
of semicrystalline materials.
The Akroflocks are said to benefit rubber compounders in seals, where flock increases tear strength and improves dimensional stability
and stiffness; rolls, where nylon and cotton flocks impart abrasion and chip resistance; belting, where cotton flock, applied prior to cure, prevents air trapping with minimum effect on adhesion; molded goods, where fiber and wood flours prevent cut growth and increase tear and modulus, and where they also allow air to bleed from the stock, which prevents blisters; and in molded open cell sponge, where wood and cotton flocks prevent cell wall collapse after cure.
GE also says Extem has better creep resistance and dimensional stability
under load at high temperatures than other high-end crystalline thermoplastics like PPS and PEEK.
Functionality and dimensional stability
are of prime importance in many products, but especially when it comes to seals," says Dennis Askew, New Business Development account manager.
