What is the difference between ACM and NBR rubber?

ACM vs NBR rubber properties, oil resistance, temperature range and cost, automotive seals and O-rings side by side.

Choosing the right rubber material is critical for reliable performance in engines, transmissions, and industrial machines. I have seen both ACM and NBR rubbers used for seals and hoses, but selecting the wrong one can lead to early failures and costly repairs. ACM (Acrylic Rubber) is valued for its superior resistance to heat and synthetic […]

What is ACM rubber used for?

ACM rubber parts set, transmission seals and gaskets, various automotive hoses and sealing rings, industrial application layout.

Many engineers face problems when oil or heat causes rubber seals and hoses to crack or fail. I have seen costly breakdowns in transmissions and engines simply because the wrong material was chosen for these demanding environments. ACM rubber (acrylate rubber) is mainly used for automotive transmission seals, hoses, gaskets, and other parts that must […]

What is AEM rubber hose?

AEM rubber hose , automotive and industrial hoses in various sizes, black synthetic elastomer tubing on white.

Many automotive and machinery failures start with cracked or hardened hoses. I have seen costly downtime and repairs when hoses can’t stand up to heat, oil, and constant flexing. This is where AEM rubber hoses become the smart solution for demanding environments. AEM rubber hose is a flexible hose made from ethylene acrylic rubber (AEM), […]

What is AEM rubber used for?

AEM rubber components set, black AEM hoses, sleeves and O-rings, displayed on white background for automotive sealing uses.

Choosing the right rubber for heat and oil resistance is a challenge. I have worked with many customers whose seals and hoses failed early in engines or machinery because the wrong material was selected. AEM rubber offers a reliable solution for many demanding applications. AEM rubber (ethylene acrylic rubber, also known as Vamac®) is mainly […]

What is AEM Rubber?

AEM rubber automotive hoses and seals, various black AEM molded parts and vibration dampers, arranged for industrial application.

Many engineers and buyers face issues with seals and gaskets that break down in high temperatures or oil-rich environments. I have seen countless cases where using the wrong rubber material led to costly failures and urgent replacement needs. AEM rubber, also known as ethylene acrylic rubber or Vamac®, is a specialty synthetic elastomer that offers […]

What is the process of rubber molding?

Rubber molding process, steel mold and finished rubber bellows, showing preform, mold cavity, and final molded parts for industrial use.

I know how confusing rubber molding can seem at first, especially if you have never watched the process in person. Many buyers are surprised to learn how much detail goes into making even a simple rubber part. The rubber molding process involves placing uncured rubber into a mold, applying heat and pressure, allowing the rubber […]

What is the difference between rubber and plastic molding?

Rubber molding and plastic injection molding process comparison, industrial machines side by side, operator handling rubber part, plastic mold open on machine

Many people think rubber and plastic parts are made the same way, but I often see costly design errors when teams don’t understand the key differences between rubber and plastic molding. Rubber molding uses heat and pressure to cure flexible, elastic materials, while plastic molding shapes rigid or semi-rigid materials by melting and cooling them. […]

What is Rubber Molding?

Compression molding create molded rubber parts

Many engineers struggle with getting custom rubber parts that fit and perform as needed. I have seen delays and failures simply because people don’t understand the basics of rubber molding. Rubber molding is a manufacturing process where raw rubber is shaped into final products using heat and pressure in a mold cavity. This process creates […]

What is the shrinkage rate of silicone rubber?

Silicone O-ring shrinkage rate chart, three red O-rings labeled 2%, 2.5%, 3%, visual comparison of different shrinkage percentages, white background

Many buyers expect molded silicone rubber parts to fit perfectly, but sometimes they are shocked to find the parts are smaller than designed. I have seen entire batches scrapped simply because no one planned for silicone’s unique shrinkage rate. Silicone rubber typically has a shrinkage rate of 2% to 3% during molding. The exact rate […]

What is the shrinkage rate of rubber?

Rubber O-ring shrinkage rate chart, EPDM 1.5%, NBR 1.4%, silicone 3%, material comparison with black and red O-rings, white background

Anyone who has ordered custom-molded rubber parts knows the pain of receiving pieces that do not fit. I have seen projects delayed or rejected because no one considered rubber’s shrinkage rate in the mold design. The shrinkage rate of rubber typically ranges from 1% to 3%, depending on the rubber type, formulation, and molding conditions. […]
