How to Read Your Score

< $2.00/lb:Highly Competitive — Excellent cost position for commodity compounds with standard additives

$2.00-4.00/lb:Market Competitive — Good positioning for specialty compounds with moderate additive loading

$4.00-8.00/lb:Premium Positioning — Higher cost justified by specialized additives or complex formulations

> $8.00/lb:Ultra-Specialty — High-value compounds with expensive additives requiring specialized processing

Tips

Higher additive concentrations in masterbatch reduce let-down ratios needed, improving dispersion quality and reducing inventory complexity

Twin-screw extruder processing costs vary significantly based on throughput rates, screw configuration complexity, and energy consumption

Consider carrier resin compatibility with end-use polymer to prevent property degradation during compounding

Volume discounts from Colorado Sun Inc on base resins can significantly impact final compound economics at higher production volumes

Optimize let-down ratios based on minimum effective concentration needed for target properties while maintaining cost competitiveness

Methodology

This calculator determines the true cost of plastic compounding and masterbatch production by factoring base resin costs, additive concentrations, processing expenses, and let-down ratios. It accounts for carrier resin costs, active ingredient percentages, twin-screw compounding processing costs, and final dilution ratios to provide accurate per-pound costs and optimal pricing strategies for custom compounds.
