The choice of what seal system to have on the wrist of their drysuit can be a bit bewildering at first. On the Nova suit the default (what you get as standard on the suit if do not select an “option”) is bottle seals standard weight. We will fit the size that is appropriate to the wrist size you provide. These seals are great allrounders comfy and generally very dry. So why change them? Let’s go through the options. TRP Polymer Solutions offers a wide range of high-performance seal materials. Our highly skilled technical experts are adept at formulating innovative sealing solutions, overseeing the development of your product from the design stage through to full production. We can recommend the most appropriate polymer material for your sealing application, providing a functional, durable and reliable seal product.

With all these negatives why would you want one? Well, they are very comfortable (once on) and very warm, also they do not “rot” like latex so last longer. They do get little spits and chunks gauged out of the skin surface, but they can mostly be nursed to the end of the season with field repairs when they can then be replaced. They very rarely fail catastrophically so you can’t dive unlike latex. Flame Retardant Neoprene seals are grey in colour, can handle continuous temperatures from -40°C to 115°C and subject to more vigorous fire testing ( FMVSS 302, UL94, AFNOR P9750), this makes the material ideal for use within construction and transport applications where a flame-resistant barrier may be required. Temperature Resistant: They exhibit good temperature resistance, maintaining their sealing properties across a wide range of temperatures, from extreme cold to moderate heat. Finally, we have Option – Kubi Fitted Dry Cuff System. The kubi rings are alloy not plastic and come in four sizes so you choose the ring size to your hand size. Very tough very reliable but this engineering comes at a price, but a price that if you wear drygloves on almost all dives and you do a lot of dives that is worth paying. We would always recommend that you also select Supplement for Siflex (silicon seals).Neoprene rubber is widely used for weatherstripping within the construction sector, where its UV and weather resistance properties make it an ideal solution for providing effective sealing and insulation against the outdoor elements. The construction industry also relies on Neoprene rubber for use in expansion joints, serving to accommodate movement and prevent structural damages caused by thermal expansion and contraction and building infrastructure. Marine & Aquatic: Flame retardant neoprene rubber seals can handle continuous temperatures of -30°C to +100°C, this material meets the test requirements of the flammability standard UL94-V0 and is in line with ISO 340. Flame retardant neoprene rubber sheets are also tested in accordance with anti-static BS 490. In 1930, an American chemist named Arnold Collins, who was part of DuPont’s research group, made his discovery after Investigating the by-products of divinylacetylene (the vinyl derivative of acetylene). After World War II, DuPont invested in a neoprene plant to meeting the increasing demand for neoprene rubber. How is neoprene made? Each grade of Neoprene rubber offers specific advantages, catering to different application requirements. Selecting the appropriate material based on the desired properties, performance, specifications, and environmental conditions of the intended application is crucial. Understanding the specific benefits of each grade of Neoprene allows for informed decision-making when choosing the most suitable solution for your project. Why use Neoprene Rubber?

Neoprene rubber is one of the most popular elastomers on the market due to its long list of benefits, however there is one key disadvantage worth noting. Neoprene rubber is not resistant to oxidising acids and harsh chemicals, therefore applications involving these fluids would require another rubber solution. Is Neoprene rubber hard or soft? Weather and Ageing Resistance: Neoprene rubber can maintain its integrity and performance even in harsh outdoor environments, ensuring longevity and reliability. This is due to the elastomers resistance to ozone, UV radiation and weathering in general. There are various grades of Neoprene rubber available including Commercial Grade Neoprene Rubber, British Standard BS2752 Neoprene Rubber, Expanded Neoprene/EPDM Closed-Cell Sponge Rubber, Flame Retardant Neoprene Rubber and Neoprene/Nylon Insertion Diaphragm Rubber. Flexibility: Neoprene gaskets are flexible and conformable, allowing them to adapt to irregular surfaces and maintain a secure seal. Neoprene is a very popular gasket material due to the combination of physical properties and resistance the material offers. Not only does neoprene provide great weathering, ozone and fuel resistance it also features combustion resistance across many different grades. This unique combination of properties ensure that our neoprene rubber gaskets are suitable for use in almost all applications or working environments.
Materials
Excellent Chemical Resistance: Neoprene rubber exhibits remarkable resistance to a wide range of oils, greases, solvents, and chemicals. This makes it suitable for applications where exposure to such substances is common, providing long-lasting performance and reliability. In the marine and aquatic domain, Neoprene rubber’s water resistance and insulation properties make it the go-to choice for equipment including wetsuits, gloves, boots and other protective gear used for watersports and diving. It’s also well suited for seals and gaskets found in marine equipment or boats, ensuring reliable performance and preventing water ingress that could potentially cause damages. Electrical:
