Below are some of the benefits and advantages of molded seals:


Filling the Gap Between Rubber and Plastic

Plan Tech’s seals are outstandingly able to withstand more loads than rubber because they are harder than rubber and yet more flexible than plastics. Their flexibility is accountable for their strength and remarkable ability to resist impact.


Abrasion Resistance

Seals are the perfect choice for applications against severe wear regardless of low temperature. For some decades now, they have been the most used materials for environments that are highly abrasive owing to their super ability to resist abrasion. No other form of elastomers, metals, and plastics has a better abrasion resistance than polyurethanes. Plan Tech’s seals abrasion resistance ability is rated to be 10 times better than what other materials can provide.


Oil and Chemical Resistance

Like their abrasion resistance ability, the properties of polyurethane seals are highly capable of resisting oil and chemicals. This enables them to maintain stability (with minimal swelling) in water or oil etc. If you are looking for elastomer materials to use in subsea, then polyurethanes should be your ideal choice for urethane seals.


Affordable manufacturing process

Productions such as prototypes as well as one time products or one-off parts are often manufactured using polyurethanes.


Polyurethane Resilience

Resilience is generally a product of hardness. Polyurethanes are the perfect choice for elastomer applications that can absorb shock. They have a high vibration frequency or outstanding ability for quick recovery. Their remarkable resilience ensures Plan Tech’s seals are very tough materials!


Made In USA Urethane Seals


Plan Tech fabricates custom tight tolerance seals with a variety of thickness, colors, and hardness. Thickness ranges from .020’’ to ½” are most commonly water jet cut with a thickness tolerance of +/-.010 and are typically supplied in a durometer range between 60A and 90A. We routinely test according to ASTM standards to meet the tight tolerance custom molded seals specifications. Custom thickness, colors or FDA requirements are also available or any other durometer from 20A to 75D. Another common molding process at Plan Tech is compression molding custom seals. This allows us to have a radius or details on both faces of the part. Between molding, water jet cutting or compression molding we can handle any volume or size of your requirements for custom rubber seals!


Polyurethane is a great choice of material for seals due to being chemical and abrasion resistant with a temperature range from -20F to 180F. Custom polyurethane seals consistently outperform plastic, rubber, and steel in its capacity to resist harsh environmental factors such as abrasion, heat, oil, acid, solvents and many chemicals. We also incorporate a full line of polyurethane additives for enhanced performance of our tight tolerance seals!
