Custom Profiles and Seamless Spliced Assemblies for Demanding Sealing and Insulation Applications

Extruded Rubber Parts

Introduction

Eutsler Technical Products can produce custom extruded elastomer profiles, tubing, cords, and spliced assemblies designed for precision sealing, insulation, vibration control, and mechanical protection in critical industrial and energy applications.

Our Extrusion & Splicing Technology combines in-house compounding, controlled extrusion, vulcanization, splicing, and quality validation, all under ISO 9001:2015-certified processes.
We deliver continuous-length and custom-shaped extrusions with engineered cross-sections and seamless splices that maintain dimensional accuracy, consistent mechanical properties, and full environmental resistance.

Core Design Features

Precision Extrusion Technology

Continuous extrusion of custom profiles, tubing, and cords in virtually any cross-section
Controlled die temperature, pressure, and screw speedfor uniform density and surface finish
Multi-material co-extrusioncapability for hybrid seals and bonded layers

Seamless Vulcanized Splicing

Precision butt, step, and corner splicesusing heat, adhesive, or molding vulcanization
Achieves bond strength equivalent to the parent material—no weak points or leakage paths
Tool-free or molded splicing depending on geometry, durometer, and environment

Engineered Cross-Sections

Custom extruded shapes designed for compression, sealing, insulation, or protection
Profile consistency maintained through in-line laser dimensional scanning
Wall and cross-section tolerances controlled to ±0.005–0.015 in

Material & Compound Options

Eutsler develops and mixes elastomer compounds internally to ensure optimal extrusion performance, cure uniformity, and long-term durability.

Application Type	Elastomers	Key Attributes
General Purpose	NR, SBR, CR	Excellent resilience and flexibility
Oil & Fuel Resistant	NBR, HNBR, ACM	Excellent hydrocarbon and amine resistance
Chemical & High-Temp Resistant	FKM, TFEP	Broad chemical resistance and stability up to 500 °F
Steam & Water Resistant	EPDM, CSM	Excellent hot water, ozone, and steam resistance
Low-Temperature Flexible	VMQ, FVMQ	Maintains elasticity down to –75 °F
Low-Permeability & Damping	IIR, BIIR	Excellent gas retention and isolation properties

All compounds are tested for rheology (ASTM D5289), tensile (ASTM D412), and compression set (ASTM D395) to ensure extrusion consistency and predictable field performance.

Extrusion & Processing Capabilities

Extrusion Lines

Single-screw extrusion systems for small to large profiles
Cross-section repeatability within ±0.003–0.010 in

Cutting & Forming

Precision cut-to-length with ±0.010 in tolerance
Coil, ring, or straight-stick packaging options

Splicing Processes

Hot vulcanized splicing:Provides seamless joint equivalent to parent compound
Cold chemical splicing:For low-volume or specialty assemblies
Molded corner splicing:Ensures exact geometry and surface alignment for gasket frames

Reinforced joint options: Fabric, wire, or insert reinforcement for structural strength

Testing & Quality Control

Every extrusion and splice batch is validated through Eutsler’s in-house quality laboratory:

Property / Test	ASTM Standard	Typical Range / Target
Hardness	D2240	30 – 80 Shore A
Tensile Strength	D412	1,500 – 4,500 psi
Elongation	D412	150 – 700 %
Tear Strength	D624	100 – 400 ppi
Compression Set	D395	< 25 %
Heat Aging	D573	≤ 25 % property change
Fluid Immersion	D471	< 25 % volume change
Splice Strength	D429	90–100 % of parent material strength
Dimensional Control	—	±0.005–0.015 in cross-section

All parts are visually inspected for surface uniformity, voids, and joint integrity, with SPC-based statistical monitoring for production runs.
