Overview. Polyphthalamide (PPA) is a semi-crystalline, aromatic polyamide. Compared to nylon 6/6, it is stronger, stiffer, less sensitive to moisture, and has higher thermal capabilities. It has significant chemical fatigue and creep resistance.
What is PPA in polymers?
Polyphthalamides (PPA) Materials Polyphthalamide, or PPA is a high-performance resin and member of the nylon family with exceptional thermal, mechanical and physical properties. It is hygroscopic, opaque, semicrystalline and can be used in injection molding.

Polymer Name | Min Value (g/cm3) | Max Value (g/cm3) |
---|---|---|
PPA – Polyphthalamide | 1.110 | 1.200 |
PPA, 33% Glass Fiber-reinforced – High Flow | 0.140 | 0.150 |
PPA, 45% Glass Fiber-reinforced | 1.580 | 1.600 |
PPE – Polyphenylene Ether | 1.040 | 1.100 |
What is ultramid?
Ultramid® A (unreinforced) is the material with the greatest hardness, rigidity, abrasion resistance and thermostability. It is one of the preferred materials for parts subject to mechanical and thermal stresses in electrical, mechanical and automotive engineering.
What is PA material?
PA material, polyamide or commonly called nylon, is manufactured by Ensinger in standard stock shapes for machining in sheet, rod and tube. There are often numbers associated with nylon plastics types such as 6, 66, 12 and 46.
What is PA6T 66?
DuPont™ Zytel® HTN High Performance Polyamide Resin — Zytel® HTNFR52G30NHF BK337 — PA6T/66-GF30FR. Zytel® HTNFR52G30NHF BK337 is a 30% glass reinforced, flame retardant, lubricated high performance polyamide resin with improved flow. It is also a PPA resin and it uses a non-halogenated flame retardant.
How is PPA made?
A power purchase agreement (PPA) is a contractual agreement between energy buyers and sellers. They come together and agree to buy and sell an amount of energy which is or will be generated by a renewable asset. PPAs are usually signed for a long-term period between 10-20 years.
What is PBT polymer?
PBT (polybutylene terephthalate) is a strong and stiff engineering plastic with excellent machining characteristics, chemical resistance, and bearing and wear properties.
What is PPA water?
Hot water moldable Polyphthalamide (PPA) is a semi-crystalline, aromatic polyamide. This material has the same advantages and limitations as the RTP 4000 Series. However, this material can achieve maximum crystallinity at lower mold temperatures.
What type of plastic is PE?
polyethylene (PE), light, versatile synthetic resin made from the polymerization of ethylene. Polyethylene is a member of the important family of polyolefin resins.
Is Ultramid A nylon?
Ultramid polyamides (Nylon) are exceptional for their high mechanical strength, rigidity and thermal stability. Moreover, Ultramid polyamides afford good impact resistance even at low temperatures, advantageous sliding friction properties and problem-free processing.
What is grilamid?
Grilamid® is a high-performance polyamide developed and manufactured in Switzerland, and is a revolutionary new transparent plastic with exceptional properties. Grilamid® long-term resistance to UV degradation matches their impact enhanced Acrylic used in most HELLA LED lamps.
Is PA a nylon?
What is PA fiber?
PA or Polyamide is a hugely important part of the synthetic fibre industry. PA6 fibres are tough and possess high tensile strength as well as high elasticity.
Is nylon 66 the same as PA66?
While, Polyamide 66 (PA66) or Nylon 66 is one of the most popular engineering thermoplastics and is majorly used as a replacement to metal in various applications.
What is difference between nylon 66 and nylon 610?
At higher temperatures, like 180°c, nylon 6/6 shows markedly better heat age strength at 11.5kg, compared to nylon 6 of only 2.5kg. The fibres of nylon 66 are 33% more resistant to abrasion than nylon 6, withstanding up to 60,000 cycles compared to 40,000 in the case of nylon 6.
What is PPA price?
The PPA rate usually increases by 1-5% each year for the contract term (i.e. a price escalator) to account for gradual decreases in system operational efficiency, operating and maintenance costs, and increases in the retail rate of electricity. PPAs are generally long-term agreements of 10-25 years.
What is a green PPA?
They are called “Green Power Purchase Agreements” (Green PPAs). These are green power purchase agreements from renewable energies which operate over the medium or long term (5 to 20 years). Clients who purchase these have access to a reliable, certified green energy at a predefined, stable rate.
What is PBT made of?
polybutylene terephthalate (PBT), a strong and highly crystalline synthetic resin, produced by the polymerization of butanediol and terephthalic acid.
Is PBT brittle?
Polybutylene terephthalate (PBT) is a brittle polymer with the disadvantage of low impact toughness, so it is not easy to meet the requirements of both high tensile strength, flexural strength, and high impact strength.
Is PPA a nylon?
PPA, High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide (nylon) family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids.
What is difference between PE and HDPE?
Significantly, HDPE pipes are durable and flexible and can be used for more than 50 years without any complications. On the other hand, polyethylene or PE pipe is the most common and widely used plastic globally. It’s a common polymer used for packaging mainly plastic bags, films, bottles and geomembranes.
Is PE material strong?
Polyethylene is of low strength, hardness and rigidity, but has a high ductility and impact strength as well as low friction.
