Selecting a Jacket Material
Parker Multitube Instrument and Heat Trace Tubing Products are currently offered with a choice of several
jacket materials. The purpose of this report is to present the main properties of the standard thermoplastics
and to discuss selection factors for various Multitube products.
The following table provides a summary of the main properties of the standard jacket materials. Additional
details can be provided on request to the factory.
Material Specifcations for Jackets:
Flame Resistant Polyvinyl Chloride (FR PVC)
Jacket: Black, 105C rated, fame-resistant, corrosion-
resistant thermoplastic compound with excellent
low-temperature fexibility properties. Meets or
exceeds ASTM D-1047, IPCEA S-19-81, IPCEA
S-61-401.
Thermoplastic Rubber (TPR) Jacket: Black,
corrosion- and weather-resistant thermoplastic rubber
material.
Flame Resistant Thermoplastic Elastomer
(FR TPE) Jacket: Black, fame-retarding
thermoplastic elastomer compound. UL94-V-0 fame
classifcation. Passes IEEE vertical fame test. Meets
ASTM D-2671 copper mirror corrosion test standards.
Polyurethane (PUR) Jacket: Black, abrasion-
and corrosion-resistant compound with excellent
hydrolytic stability.
Flame Resistant Polyurethane (FR PUR) Jacket:
Black, fame-retarding, abrasion- and corrosion-
resistant compound which exhibits excellent low-
temperature properties, hydrolysis resistance, and
fungus resistance which has a UL94 fame test rating
of V-0.
Low Density Polyethylene (LDPE) Jacket: Black,
weather-resistant grade, high molecular weight, low-
density compound which meets the requirements
of ASTM D-1248-72 as follows: Type I, Class A,
Category 4, Grade E5.
Flame Resistant Polyethylene (FR PE) Jacket:
Black, weather-resistant, high molecular weight,
fame-resistant polyethylene compound which meets
the UL94 V-2 fame classifcation.
