From 10% to 30% Glass Fibre: Choosing the Right PC Grade for Industrial Components

When a plastic component needs higher stiffness, impact strength, dimensional stability or flame resistance, the choice of polycarbonate grade becomes important. The glass-fibre level is one of the first factors manufacturers should consider, but it is not the only one. Flow, mold release, UV stabilization, flame performance and component design can all influence the right material.

Kapoor Sales Corporation offers a broad selection of PC glass filled resin grades from LEXAN™ and LOTTE INFINO™, giving manufacturers access to 10%, 20% and 30% glass-filled materials along with specialized flame-retardant and thin-wall options.

Which Glass-Filled PC Grade Fits Your Requirement?

A quick comparison makes the range easier to understand:

Grade Range	Reinforcement	Key Benefit	Typical Requirement
10% GF	10% glass fibre	Balanced reinforcement and impact performance	General reinforced components
20% GF	20% glass fibre	Greater stiffness and dimensional stability	More demanding structural parts
30% GF	30% glass fibre	Higher reinforcement and rigidity	Load-bearing components
Thin-Wall	10% to 30% GF	Reinforcement with thin-section capability	Compact electrical and industrial parts

• Mold-release options

• Non-halogenated options

• Renewable-feedstock option with LEXAN™ 3412ECRRW

30% GF Grades for More Demanding Components

For applications where higher glass reinforcement and rigidity are required, 30% GF grades provide another level of material selection.

Available grades

• LEXAN™ 3413HF

• LEXAN™ 3413R

• LEXAN™ 3413R Black

• LEXAN™ 3413R Natural

Grade benefits

• 30% glass-fibre reinforcement

• High stiffness

• Flame-retardant options

• Mold-release capability

• Natural and black material options

• High-flow option with LEXAN™ 3413HF

Flame-Retardant and Thin-Wall PC Options

Kapoor Sales Corporation's range also covers applications where flame performance is a primary requirement. Available FR grades include LEXAN™ 943A/111, 943/701, 943 Siemens Grey, 943 Dark Grey, 940A/111, 940/701, 945U, 945 and 945A.

For thin-wall components, the range includes LEXAN™ 3412ECR, 505RU, 515RU, BFL2015, ML3019, 3412ECRRW, 3413HF, 500R, 503R, 505R and 525RU.

These options cover different reinforcement levels and characteristics such as high viscosity, UV stabilization and non-chlorinated/non-brominated flame retardancy.
