PPAP Production Part Approval Process — Key Points You Need to Know In the sealing industry, PPAP (Production Part Approval Process) is more than a quality formality. This is especially true for oil seals and O‑rings. It ensures your rubber seals meet exact specs for material, size, hardness, and performance. This helps prevent leaks, assembly failures, and costly downtime. It

O-ring color coding system, labeling specifications and batch management

Maggie February 6, 2026 March 4, 2026

O-ring color coding system, labeling specifications and batch management Summary Many customers encounter key pain points in the selection, use, storage, and after-sales traceability of O-rings, including the inability to distinguish specifications and materials among O-rings with the same appearance; misuse due to confusing labels and inability to trace batches when quality problems occur. These issues not only affect production

How effective is polyurethane material for seals?

Maggie January 29, 2026 March 4, 2026

In the field of industrial sealing, O-rings and oil seals are core components, and their material selection directly determines the sealing performance, service life, and operating costs of the equipment. As a high-performance polymer material, polyurethane (PU) has recently replaced traditional rubber and has become the preferred material for O-rings and oil seals under high-pressure and high-wear conditions. Core performance advantages of polyurethane

What is vulcanized rubber? A complete guide

Maggie January 14, 2026 March 6, 2026

What is vulcanized rubber? Vulcanized rubber refers to a stable polymer material formed by the vulcanization process of natural or synthetic rubber. Before the advent of vulcanization, raw rubber was directly extracted from the sap of rubber trees. It was sticky, soft, low in strength, and prone to aging and deformation. It was also sticky at high temperatures and brittle
