Aerospace & Military Industry
Learn MoreWith over 39 years of industry experience, National Plastics & Seals is a leading manufacturer of custom CNC machined plastic parts for military and aerospace applications. We offer a broad range of high-quality products, including aircraft interior plastics.
The components used in aircraft and spacecraft construction are both fragile and complex. Connectors, terminators, and circuit boards need protection from ultraviolet light, dust, and chemicals. Professional heat shrink products provide essential protection from moisture, strain, and abrasion of crucial cables and wires.
The aerospace and military industries demand strict adherence to unique requirements for manufacturing components and materials used in specific applications. Various types of industrial plastics can be used to meet these stringent specifications, with each plastic offering distinct properties and advantages.
We supply the aerospace and military industries with the following materials to construct various parts and components:
Medical Industry
Learn MoreNational Plastics & Seals is the go-to source for precision-machined parts designed for the medical industry. Our top-quality plastics provide long-lasting, durable performance while meeting the stringent requirements of this industry.
Medical-grade heat shrink tubing is constructed without heavy metals and is ideal for covering medical instruments and devices of varying diameters. Often made of polysulfone or Udel®, the flame-retardant, durable heat shrink tubing comes in various colors and styles and offers excellent chemical, physical, and electrical properties.
Here is an overview of the most common plastics we supply to the medical industry:
-
Polysulfone (Udel®)
Polysulfone (Udel®)
A polyether-containing polymeric material that has a high melting point, good mechanical properties, and resistance to solvents, chemicals, and heat. It can withstand harsh environments and resist prolonged hydrolysis, making it ideal for medical sterilization and fluid-handling applications.
-
5% Boron-Filled HDPE
5% Boron-Filled HDPE
A reliable, innovative material that can substitute lead shielding materials in X-ray applications. 5% boron-filled HDPE is also lighter and more cost-effective than lead.
-
Polyetherimide (Ultem®)
Polyetherimide (Ultem®)
A unique thermoplastic offering superior durability, chemical resistance, and performance compared to other medical plastics. Ultem® is well-suited for healthcare applications requiring temperature stability.
-
PEEK
PEEK
This biocompatible material offers excellent flexibility and strength and is often used instead of metal for dental implants and hip replacements.
Oil & Gas Industry
Learn MoreNational Plastics & Seals has extensive experience working with the oil and gas industry, with capabilities that include fabricating and machining plastic components for a wide array of applications.
One of our key products is heat shrink tubing, which is necessary in the oil and gas industry for securely insulating and splicing sensitive wiring in harsh environmental conditions. Our heat shrink tubing is renowned for its purity, mechanical strength, and thermal resistance of up to 500 °F (260 °C). We also provide customizable stock products such as sheets, rods, tubing, and rubber components.
- HDPELearn More
Polyethylene based materials are suitable for a variety of environments. They are chemically resistant, have a low coefficient of friction, act as non abrasive wear surfaces and have excellent impact properties.
- PVCLearn More
Polyvinyl chloride (PVC) is one of the most popular plastics on the market. It is very resistant to chemicals and corrosion and is used in pipes, cable and wire arrays, and roofing materials, among many other applications.
- PPLearn More
A type of polyolefin, polypropylene is a hard non-toxic plastic that is highly resistant to chemicals and microbial growth. It is typically used in process piping and plumbing fixtures.
- PCLearn More
Tougher than acrylic, polycarbonate is highly resistant to impacts and extreme temperatures.
- PEILearn More
Polyetherimide (PEI), also known as Ultem®️, is an engineering plastic with exceptional mechanical strength, excellent electrical insulating properties, and resistance to a variety of chemicals.
Food & Beverage Industry
Learn MoreNational Plastics & Seals provides the food and beverage industry with plastic fabrication for various food processing products and parts using food-grade and agricultural plastics. We offer heat-shrinkable sleeving and high-performance fluoropolymer tubing for food and beverage applications. The unique properties of these materials set them apart from PE, PVC, and other general-purpose plastics.
The primary advantages of using our food and beverage plastic fabrications include:
Common materials for applications in this industry include:
Marine Industry
Polyolefin heat shrink tubing provides a durable, waterproof seal against common marine elements such as sunlight, salt, acids, oil, and water. These industrial plastics also effectively meet the demands of various marine applications:
-
High-Density Polyethylene (HDPE)
Marine-grade HDPE is environmentally stabilized to withstand extreme outdoor environments. It is often used for doors, rails, docks, steps, frames, and more.
-
Acrylic/Polycarbonate
This material offers impact strength and optical clarity, making it ideal for hatches, windshields, and boat windows.
Automotive Industry
Our automotive plastics typically consist of the following materials:
-
PVC/Acetal/ABS
Used for internal transmission parts, bearings, bushings, connectors, switches, and component housings.
-
High Molecular Weight Polyethylene (HMWPE)
Used for creating moisture barriers, truck liners, and bed liners.
Automotive electrical systems rely on automotive heat shrink tubing to shield electrical components in the following areas of the vehicle:
- Acoustical systems
- Air conditioning systems
- Central locking systems
- Dashboards
- Lighting systems
- Windshield wiper systems
Building & Construction Industry
Plastics in construction and building applications consist of the following:
This material can be customized to fit any size and is often used to create dividers, patio covers, outdoor furniture, glazing, barriers, and skylights. From our Naples, FL, facility, National Plastics & Seals can produce building skylights using acrylic/polycarbonate.
Commonly used for outdoor furniture, bathroom partitions, and other barriers.
We also produce PE heat shrink materials to protect components and structures in weatherization and other environmental containment uses.
