Frequently Asked Questions (FAQ)

To assist your engineering and procurement teams in making informed decisions, we have compiled detailed answers to the most common technical inquiries regarding our monomeric carbodiimide hydrolysis stabilizer.

What is the primary advantage of using the impregnation method over traditional compounding?

Impregnation allows for the application of hydrolysis resistance to finished or semi-finished parts without altering the original polymer formulation or adjusting high-temperature extrusion settings. It is ideal for complex components that require a concentrated protective layer without affecting internal mechanical flexibility.

How does the purity level impact the final polymer product?

Ultra-high purity ensures that there are no volatile impurities that could cause unwanted discoloration, odors, or secondary chemical reactions during high-heat processing. This guarantees a clean, consistent, and aesthetically perfect final product, which is especially critical for transparent or light-colored plastics.

Can this stabilizer be used in biodegradable plastics like PLA and PBAT?

Yes, it is highly effective in biodegradable polymers. It carefully regulates the degradation timeline, preventing premature breakdown during the product's useful life in humid conditions, while still allowing for designed end-of-life biodegradation once disposed of in proper composting facilities.

Why is the product's insolubility in water considered a benefit?

Water insolubility ensures that once the stabilizer is embedded within the polymer matrix or applied via impregnation, it will not be washed out or leached away when the final product is exposed to rain, high humidity, or submerged environments, providing permanent, long-lasting protection.

What are the critical storage requirements to maintain the stabilizer's efficacy?

The powder must be kept in a tightly sealed container in a cool, dry location. Because it is highly reactive with moisture (which is exactly how it stops hydrolysis in polymers), exposing the raw powder to ambient humidity will cause it to react prematurely, reducing its effectiveness before it enters your production line.
