Material Transparency
Perfluoroelastomer FFKM O-Rings are often considered to be high-risk products due to their higher unit price. Unfortunately, unscrupulous traders may attempt to deceive buyers by mixing them with low-cost FKM rubber or using illegal additives to inflate profit margins. At KATON®, we prioritize material transparency, taking proactive measures to combat product fraud. We publicly disclose our material testing and verification methods to ensure the authenticity and integrity of our FFKM O-Rings, safeguarding our customers from counterfeit products.

Price Transparency
Since 2023, MAXMOLD® has implemented a transparent pricing strategy for all products. We firmly believe in the importance of establishing a fair market pricing system for FFKM O-Rings. Many companies either refuse to publish prices online or require customers to provide detailed information before disclosing prices, aiming to take advantage and provide different pricings to different customers. However, this is not a sustainable approach. By providing open and transparent pricing, we strive to create a fair market and enable our customers to make informed decisions, ensuring fairness and integrity in every transaction.
