Why doesn’t the slow-rebound product I made with my own adjusted formulation have a slow-rebound effect?

We understand the difficulties you’re facing in developing slow-rebound products. Failing to achieve the desired slow-rebound effect with your own adjusted formulation is a common but very challenging problem. The performance of slow-rebound (memory foam) products highly depends on the precise ratio of polyurethane raw materials, process parameters, and the professionalism of the formulation design. Key technical points involved include:

Raw material selection and ratio: The slow-rebound effect mainly stems from the synergistic effect of special polyether polyols, isocyanates, and functional additives. When adjusting the formulation yourself, any deviation in the proportion or type of any component will lead to insufficient open-cell structure, too fast or too slow rebound speed, poor support, and other problems.

Process sensitivity: Subtle changes in temperature, pressure, mixing efficiency, and curing conditions can seriously affect the pore structure and mechanical properties of the final product.

Stability and consistency: Even if the experiment is successful, batch production may still result in unstable effects due to differences in raw material batches or process fluctuations.

Why is it not recommended to continue adjusting the formulation yourself?

High time cost: It requires repeated testing of formulations and processes, which is a lengthy process.

High technical threshold: It requires a deep understanding of polyurethane chemistry and extensive practical experience.

Resource waste: Each experiment consumes raw materials, manpower, and production capacity, and the overall cost may increase rather than decrease.

How to quickly solve the problem and achieve efficient production?

We recommend that you choose a professional one-stop solution – Jiaxin’s GST slow-rebound composite material.

By choosing Jiaxin’s GST slow-rebound composite material, you can:

✅ Ready to use, no need for repeated adjustments
We provide a complete composite material system (including polyether, isocyanate, and supporting additives) that has been precisely designed and fully verified. You only need to mix them in the correct proportions for direct production, eliminating the tedious process of self-development and debugging.

✅ Stable performance, immediate results
The GST series is designed for high-quality slow-rebound products, ensuring that the product has:

Excellent slow-rebound characteristics: Conforms to body curves, rebounds slowly, and provides comfortable support.

Consistent open-cell structure: High open-cell rate, good breathability, avoiding stuffiness. Excellent Physical Properties: Strong durability, high fatigue resistance, and resistant to deformation even with long-term use.

✅ Simplified Production, Reduced Risk

Wide processing window, insensitive to changes in production conditions, making operation easier.

High batch-to-batch consistency ensures consistent product quality.

Our technical support team provides production guidance to help you get started quickly.

✅ Save on Overall Costs
Although the unit price of the composite material may be slightly higher, it eliminates the waste of raw materials, time investment, and technical labor costs associated with repeated testing, allowing you to launch your products to market faster and more reliably.

Next Steps:
