Precision fluoropolymer encapsulation for materials including glass, metal, silicone, Viton®, and rubber – only from Holscot.
Holscot is a trusted industry leader in developing bespoke manufacturing solutions. One of our specialist capabilities is extrusion-based fluoropolymer encapsulation of linear materials — offering consistent wall thickness and significant cost savings over traditional shrink-fit methods.
The Holscot team has pioneered a technique to encapsulate linear items in a uniform fluoropolymer coating, delivering both functional enhancement and economic efficiency. This process is ideal for large-volume requirements where performance and precision matter.
We can encapsulate a wide range of substrates including:
Delicate materials: e.g. glass rods or capillaries
Rough surfaces: e.g. machined metal components
Flexible or elastic materials: such as silicone, Viton®, elastomers, and rubbers
We most commonly encapsulate circular cross sections, but our unique process can also accommodate square, rectangular, D-shaped and custom profiles. Currently, we offer encapsulation for items up to 35mm in cross-sectional diameter, but are always open to collaborating on custom dimensions or challenging new applications.
Encapsulating materials in high-performance fluoropolymers such as FEP or PFA offers numerous benefits:
Exceptional chemical resistance
Low gas permeability
Non-stick / low-friction surface
Wide temperature tolerance (-200°C to +200°C depending on material)
Enhanced durability and lifespan of underlying components
This process not only improves the performance of your products but also reduces manufacturing complexity and downstream maintenance costs.
At Holscot, we encapsulate using three of the most trusted fluoropolymers:
Each material offers distinct advantages depending on your application. FEP provides outstanding clarity and is ideal for low-friction, non-stick applications. PFA offers enhanced high-temperature and chemical resistance, making it the material of choice for aggressive environments. ETFE delivers excellent mechanical strength and abrasion resistance while maintaining good chemical performance. By selecting the right fluoropolymer for your needs, we ensure your encapsulated components deliver maximum performance, longevity, and value—even in the most demanding industrial settings.
Our linear encapsulation process is already delivering value across sectors such as:
