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.

Fibre Type NTPT Thin Ply Prepreg Aerial Weights Available
CarbonFrom 15gsm  with MR70 12K
From 30gsm with typical PAN-based fibres
From 40gsm with pitch-based YSH70
From 90gsm with pitch-based K63712
GlassFrom 48gsm with 9μ S-glass fibres
QuartzFrom 30gsm with 14μ fibres
AramidFrom 20gsm
PBO and other syntheticsFrom 30gsm

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 woven (0/90) cloth prepregs, 300g and 400 g biaxials (+/-45), adhesive film, and prepreg peel ply. Other FAW materials, glass or Aramid prepregs can also be produced. If in doubt, please contact our sales team.
