Note that NTPT measures Tg using DMA T Onset point which typically gives a result 15 to 25˚C lower than Tg by Peak Tan Delta. Tg by T onset is the safest number to use, please be aware of this when comparing NTPT data with that from other suppliers.

NTPT™ has developed a unique process to spread reinforcement fibres and make the thinnest unidirectional prepreg tapes on the market, with fibre aerial weight down to 15gsm. A wide range of fibres can be processed, such as carbon, glass, quartz, aramid, and impregnated with a selection of in-house developed epoxy or cyanate ester resin systems.

|---|---|
| Carbon | From 15gsm with MR70 12K, HS40 12K, T800H 12K |
| From 20gsm with HR40 12K | |
| From 30gsm with M55J 6K | |
| From 30gsm with typical PAN-based fibres | |
| From 40gsm with pitch-based YSH70 | |
| From 90gsm with pitch-based K63712 | |
| Glass | From 25gsm with (600 tex)-glass fibres |
| Quartz | From 26gsm |
| Basalt | From 40gsm |
| Aramid | From 20gsm |
| PBO and other synthetics | From 15gsm |
Thin plies offer significant improvements in the mechanical properties of composite laminates and NTPT™ makes it possible for composite fabricators to integrate thin plies into their process while improving quality and reducing lay-up time.

While NTPT™ is naturally known for expertise in lightweight prepreg materials, we understand that these products are often part of a wider solution needing a broader material portfolio. Customers typically want to marry the performance and chemistry of thin ply with more “conventional” prepregs.
NTPT™ offers a wide range of typical reinforcements, pre-impregnated with the same resin systems as Thin Ply products. The conventional range includes UD prepreg up to 300gsm, adhesive film, and prepreg peel ply. Other FAW materials, glass or Aramid prepregs can also be produced.
