Long Fiber Reinforced Thermoplastics
to expand the use of resin to new fields
PLASTRON® LFT is resin in which reinforcing fibers (glass fibers and carbon fibers) of the same length are incorporated into resin pellets in the same direction. As a material it has both rigidity and high impact strength that were unattainable with conventional fiber-reinforced resins, thus enabling the use of thermoplastic resins in place of metals and fiber-reinforced plastics (FRPs) in a broader range of fields.
It is also a thermoplastic resin that combines different types of long fibers in various resin matrices, enabling the optimal grade selection according to the usage application.
This resin can help reduce weight in a broad range of applications, from industrial products such as industrial-use pump housings and fitting parts of civil engineering pipes to various functional parts and structural members of cars and motorcycles.
Key properties
-
High impact resistance
Three to five times the impact strength of short fiber-reinforced resins
-
High rigidity
Large volume of integrated fibers
-
Superior creep properties
Superior creep properties particularly at high temperatures
-
Broad usage temperature range
High elasticity retention at high temperatures, superior impact retention at low temperatures
-
Dimensional stability
Low warpage, few sink marks. Low linear expansion coefficient
-
Sliding & wear
Good outer appearance. Fibers have less fracture surfaces and experience a lesser amount of wear
1. High impact strength
PLASTRON® exhibits high impact strength due to the entanglement of long fibers in molded products.
In addition, impact strength improves with fiber content.
2. High rigidity
With glass fibers PLASTRON® can be filled at 60wt% in many resin bases and with carbon fibers it can be filled at 40wt%, enabling designs with even higher rigidity than conceivable with conventional fiber-reinforced resins.
3. Long-term properties
PLASTRON® also offers a significant advantage in terms of long life, including superior creep resistance.
4. Broad temperature usage range
PLASTRON® has high rigidity in high-temperature environments, and unlike typical reinforced resins its impact strength does not decline in low-temperature ranges, enabling optimal product design in a broad temperature range.
5. Dimensional accuracy
The reinforcement effect of long fibers results in lower warpage and less deformation in molded articles than with short fiber-reinforced resin.
It also has less linear expansion, enabling superior design than short fiber reinforced resin in terms of dimensional changes or warpage and deformation when joining or adhering to metal parts.
