LFT-G® PP LGF30-C | The High-Impact Upgrade for PP GF30

Product Description & Features

LFT-G PP LGF30-C material - extreme toughness copolymer LFT-G^® PP LGF30 -NG03C is the ultimate toughness upgrade for designs specifying "PP GF30". Standard PP GF30 (short fiber) is often selected for its stiffness, but it is notoriously brittle and fails catastrophically upon impact, especially in cold weather. LFT-G^® PP LGF30-NG03C is a copolymer (Copo) grade specifically engineered to solve this problem.

By combining a 30% long glass fiber network with a high-impact copolymer matrix, this material provides unparalleled durability. The long fibers create a "rebar-like" skeleton that stops cracks, while the copolymer base absorbs impact energy.

√ Extreme Impact Resistance: Offers 3-5 times the impact strength of standard PP GF30, preventing failures from drops or collisions.
√ Superior Low-Temp Toughness: Remains ductile and fracture-resistant in sub-zero conditions where homopolymer grades (including SGF PP GF30) become extremely brittle.
√ Excellent Processability: Provides a great balance of toughness and melt flow, making it ideal for molding complex, durable parts with features like snap-fits and bosses.

Case Study: Child Safety Seat Structure

A child safety seat base demonstrating high impact protection

Challenge

A premium manufacturer needed a material for their next-gen safety seat. The design had to pass stringent side-impact crash tests at both +70°C (hot car) and -30°C (winter), where standard PP GF30 becomes brittle and shatters.

Solution

LFT-G^® PP LGF30-C was chosen. The long-fiber network provided the stiffness to maintain the shell's structural integrity, while the copolymer matrix ensured high ductility and energy absorption, preventing any brittle failure during low-temperature crash testing.

Result

The design passed all safety standards with a 40% safety margin. The material's reliability allowed for a 15% weight reduction in the part, improving ease-of-use for parents and reducing manufacturing costs.

Applications for High-Toughness PP LFT

Replaces standard plastics that become brittle in freezers. LFT PP LGF30-C offers the rigidity for racking and the high impact strength to withstand forklift abuse in cold storage warehouses.

Key Questions Answered

1. Why choose this Copolymer (C) grade over the Homopolymer (H) PP LGF30?

A: The choice is all about toughness. The Homopolymer (H) grade is stiffer and has a slightly higher heat resistance. This Copolymer (C) grade is engineered for maximum impact strength and durability, especially in low temperatures. If your part will be dropped, struck, or used below freezing, this Copolymer grade is the superior choice.

2. What is the main advantage of LFT PP LGF30-C over a standard PP GF30?

A: Reliability. A standard short-fiber PP GF30 is brittle. It will shatter on impact. The long-fiber network in our LFT grade, combined with a tough copolymer base, creates a material that absorbs energy and resists fracture, dramatically increasing part longevity and safety.

3. Can this material be used for snap-fit components?

A: Absolutely. This is an ideal application. The high ductility of the copolymer matrix allows for robust, flexible snap-fit clips, while the long-fiber reinforcement provides the strength and fatigue resistance to ensure they can be used thousands of times without breaking or weakening.
