PA4T PPA - ForTii®

ForTii has unique PPA technology with high amide density. The ForTii platform includes polymers that are the highest crystalline, highest melting point and highest glass transition temperature among all PPA resulting in:

  • Best part mechanics <160°C
  • Highest peak temperature performance
  • High chemical resistance
Product overview

Explore ForTii®

ForTii is a platform of high performance semi-aromatic polyamides (PPA) based on the unique “C4” diamine technology that enables best-in-class mechanical properties due to the optimized crystallization morphology.

In addition, ForTii offers a unique balance of properties, including excellent dimensional stability, compatibility with lead free reflow soldering, and the highest stiffness and mechanical strength at extreme temperatures. The ForTii platform offers material solutions in two product groups:

ForTii®

ForTii is a PPA with high mechanical properties and good chemical resistance. The ForTii grades have a melting temperature of 325°C and a glass transition temperature of 125°C.

Key Properties:

  • Very high peak temperature resistance (HDT > 300°C)
  • Halogen free UL94 V-0 possible down to 0.2mm and CTI beyond 800°C
  • High mechanical properties below and above Tg
  • Good chemical resistance

Properties

Superior mechanical performance at elevated temperatures

The aromatic structure of ForTii combined with our unique C4 chemistry results in a polymer with a very high melting point of 325°C, complete with high stiffness across a wide temperature range. This in turn makes the heat distortion temperature for ForTii grades among the best in the industry.

Vs. Metal:

ForTii can replace metal at just 50% of the weight over a wide range of temperatures with no compromise on performance. With the highest stiffness to density ratio at elevated temperatures, ForTii Ace brings the most critical metal replacement opportunities within reach.

Vs. PPA

PPA is already a well-known material in metal replacement. The base chemistry of our ForTii MX series adds additional performance vs. standard PPAs at temperatures above Tg. If you need best in class mechanical performance, the ForTii Ace MX series, with superior mechanical performance and chemical resistance, is what you are looking for. 

Vs. PA6 & PA66

PA6 and PA66 are versatile materials for metal replacement opportunities. When mechanics at elevated temperatures (up to 150°C) are needed or the influence of moisture at moderate temperatures should be limited, Envalior’s PPA ForTii portfolio meets both challenges. ForTii Ace with a Tg of 160°C, gives superior mechanical performance even after conditioning, for example 85%RH at 85°C. This enables engineers to realize new metal replacement opportunities are not possible with PA6, PA66 or standard PPA.

Reflow Soldering for Surface Mount Technology (SMT)

In the consumer market, there is a focus on producing smaller and lighter products with more functionality. The miniaturization of electromechanical components, like connectors and sensors, requires reflow soldering technologies since the contact pitch is so small. This causes a need for materials that can resist high temperatures up to 280°C. ForTii solves this challenge thanks to its combination of high melt temperature (325°C) and low moisture absorption – which means that ForTii grades perform very well in SMT applications up to peak temperatures of 288°C. Deformation is minimal, and ForTii makes it far easier for designers to predict the warpage.

Envalior’s Fortii PPA portfolio offers a full range of reflow capable materials, ranging from HB grades to flame retardant V0 grades with full UL listing. With V0 grades Envalior ForTii ensures higher than JEDEC MSL 2 ratings on all connector and components designs. This implies a one-year shelf life without packaging.

With HB grades, Fortii and ForTii Ace can achieve the best moisture sensitivity level (MSL1) acc. IPC/JEDEC J-STD 020D for SMT. This implies unlimited shelf life without packaging. While offering the benefit of high mechanical and electrical performance of the PPA, Envalior's Fortii and ForTii Ace offer a blistering resistance almost as good as an LCP material.

Chemical resistance

Where ForTii MX1 - MX3 brings on par chemical resistance to best-in-class PPA materials, Envalior’s ForTii Ace portfolio adds an additional step-up in chemical performance. For highest chemical stability, Envalior has developed a broad portfolio in ForTii Ace, which includes injection moldable grades in 30%, 40% and 50% glass fiber. 

Creep

Vs. Metal

Whether you intend to convert your current metal design into plastic to achieve weight reduction up to 50% or you want to reduce cost by eliminating compression limiters or threaded inserts, the excellent creep performance of ForTii Ace brings new metal replacement opportunities within reach. ForTii Ace gives optimal creep performance over a wide range of temperatures.

Vs. PPA & PA66

Compared to PA66, Envalior’s PPA ForTii brings a significant advantage in terms of creep performance. ForTii outperforms low-Tg PPA materials (eg PA6T/66) and can match high Tg competitor PPAs (eg PA6T/6I). The increased performance of ForTii Ace provides additional creep performance at elevated temperatures up to 150°C or even in presence of moisture at lower temperatures.

Vs. Thermoset materials

Thermoset materials are known for their good chemical resistance as well as their stability under creep loading. With ForTii Ace we provide engineers the possibility to rethink their thermoset designs into thermoplastic material solutions. Robust processing of ForTii Ace brings better yield rates within reach, providing direct economic benefits.
