Apple Rubber offers advanced liquid silicone rubber (LSR)
pigmentation expertise for color matching and superior quality
manufacturing.
LSR Pigmentation Overview
Liquid silicone rubber naturally appears in a range from crystal
clear to opaque white. Through our advanced pigmentation process, we
can achieve virtually any desired color while maintaining the
material's exceptional physical properties. This is accomplished by
incorporating just 1-3% pigment into the LSR base material.
Key Pigmentation Specifications
Standard mixture ratio consists of 98% LSR base material and 2%
colorant by weight
Color consistency maintained across all material hardness levels
Color appearance varies with part thickness – thinner
sections appear lighter
Medical-grade colorants available meeting USP Class VI
requirements
Standard colors included at no additional cost; custom color
matching services available
Color Applications
Our color solutions serve multiple practical and aesthetic
purposes:
Part differentiation for similar components
Revision level indication
Visual verification processes
Device aesthetic matching
Important Note: Clear LSR may experience slight yellowing
over time. Consider this factor when selecting materials for
long-term applications.
Manufacturing Excellence
Our state-of-the-art manufacturing process incorporates
concentrated color paste as a third stream while LSR flows into the
press. This technique ensures uniform tinting before the molding and
curing process begins, resulting in consistent coloration throughout
the entire part.
Apple Rubber utilizes the sophisticated CAPSURE® color meter
for precise Pantone system matching. This advanced device provides
access to:
Over 10,000 Pantone colors
Corresponding sRGB, Adobe RGB, HTML, Lab, and XYZ values
Color matching capabilities
Our color testing is conducted on standardized 6″ x 6″
x 0.080″ specimens using Silopren™ LSR 2070 (70 shore A
durometer) with 2% color paste to ensure consistent results.
Comprehensive Color Solutions
With our extensive portfolio of over 70 color options and custom
matching capabilities, Apple Rubber delivers expert solutions for all
your LSR coloring requirements. Our experienced team specializes in:
Medical-grade colorant applications
Standard color matching
Custom color development
Application-specific color solutions
