Our delayed-action crosslinkers enhance network density in HR foam systems—ideal for seating, bedding, and demanding molded applications.
Crosslinkers are key additives in polyurethane (PU) foam formulations that enhance the molecular bonding between polymer chains, resulting in improved foam strength, resilience, and dimensional stability. Our range of delayed-action crosslinkers is specifically engineered for high-resilience (HR) foam systems—helping manufacturers reduce cold deformation, prevent foam breakage, and produce higher-density, longer-lasting foam products.
Unlike traditional fast-reacting systems, our crosslinkers offer controlled reactivity, allowing for better processing windows, smoother foam rise, and superior internal network structure. Whether you’re producing automotive seats, premium mattresses, or molded PU components, these crosslinkers help ensure consistent performance under mechanical stress and environmental fluctuation.
Description: Designed to work with stannous caprylate in HR foam systems. Offers excellent control over reaction time, allowing smoother foam expansion and better anti-deformation properties.

Our crosslinkers are specifically developed for high-performance polyurethane foam systems that demand durability, elasticity, and dimensional stability. Key application areas include:
Enhances structural integrity of seats, headrests, and armrests
Prevents foam collapse in high-temperature and high-load environments
Compatible with commonly used automotive foam catalysts
Enables stronger foam structure in high-density memory foams
Supports custom rebound control in sleep products
Reduces risk of sagging or deformation over time
Suitable for precision foam parts used in ergonomic furniture, office chairs, and medical supports
Ensures dimensional accuracy and consistency in repetitive production cycles
Applicable in any high-load or structural foam formulations requiring additional crosslinking
Supports unique requirements in footwear, construction foam, or insulation R&D
Crosslinkers increase the internal network density of polyurethane foams, which enhances mechanical strength, shape recovery, and long-term durability. This is especially important in high-resilience (HR) and high-load foam applications.
Our crosslinkers are optimized for systems using stannous caprylate and other common HR catalysts. For polyester-based foams or non-standard formulations, we recommend technical consultation to ensure compatibility.
