High Shrink Ratio Heat Shrinkable Tubing

1. SCOPE

This specification covers the requirements for three types of electrically insulating, extruded tubing

whose diameter will reduce to a predetermined size upon the application of heat in excess of 120°C.

They are suitable for use with Hot Melt Adhesive /97 or Sealant /226.

1.1 HRSR.

HRSR tubing is a semi rigid, flame retardant, cross-linked modified polyolefin. The standard color

is black and can be supplied with a Sealant or Hot Melt Adhesive.

1.2 HRHF

HRHF tubing is a highly flexible, flame retardant cross-linked modified polyolefin. The standard color

is black (and clear for non-flame retardant material) and can be supplied with a Sealant or Hot Melt

Adhesive.

1.3 HRNF

HRNF tubing is a semi rigid, non-flame retarded, cross-linked modified polyolefin. The standard color

is black and can be supplied with a Sealant or Hot Melt Adhesive.

2. REQUIREMENTS

2.1 Composition and Appearance

The tubing shall be fabricated from thermally stabilized, modified polyolefin and shall be irradiation

cross-linked. It shall be homogeneous and essentially free from flaws, defects, pinholes, bubbles,

seams, cracks and inclusions.

3. PROPERTIES

The tubing shall meet the requirements of Tables 1 and 2.

4. QUALITY ASSURANCE PROVISIONS

4.1 CLASSIFICATION OF TESTS

4.1.1 Qualification Tests

Qualification tests are those performed on the tubing submitted for qualificatio n as a satisfactory

product and shall consist of all the tests listed in this specification.

4.1.2 Production Routine Tests

Production routine tests shall be carried out on every batch, unless otherwise specified and shall consist

of the following: dimensions, longitudinal change, tensile strength, ultimate elongation, heat shock, low

temperature flexibility and flammability. Flammability is not applicable for HRNF and clear tubings.

5. SAMPLING INSTRUCTIONS

5.1 Qualification Test Sample

Qualification test samples shall consist of 50 feet (15m) of tubing. Qualification of any size qualifies

all sizes. The color shall be black.

5.2 Production Routine Test Samples

Production routine test samples shall consist of a sufficient length to perform all the tests in 4.1.2

selected at random from each batch. A batch shall consist of all tubing of the same size, from the same

production run and offered for inspection at the same time. Physical property tests performed at this

time qualify subsequent tubing lots produced from the same compound batch.

6. TEST PROCEDURES

Unless otherwise specified the tubing shall be recovered in a forced air circulating oven for 10 minutes

at 150 ± 2°C. All tests shall be performed without the adhesive. Uncoated samples are available upon

request.

6.1 Dimensions and Longitudinal Change

The test method shall be as specified in ASTM D 2671.

The length and inside diameter of three 250 mm long specimens of expanded tubing shall be measured.

The specimens shall be recovered and the length and inside diameter of each shall be measured. The

longitudinal change shall be expressed as a percentage of the original length. The minimum and

maximum recovered wall thicknesses shall be determined.

6.2 Tensile Strength and Ultimate Elongation

The test method shall be as specified in ASTM D 638.

For tubing of recovered inside diameter greater than 6 mm, five Type IV dumbbell specimens shall be

tested. For tubing of recovered inside diameter less than or equal to 6 mm, five tubular specimens 150

mm long shall be tested. Rate of jaw separation shall be 500 ± 10 mm per minute.

The test shall be carried out at a temperature of 23 ± 2°C.

7. PREPARATION FOR DELIVERY

7.1 Form

The tubing shall be supplied in cut lengths unless otherwise specified.

7.2 Packaging

Packaging shall be in accordance with good commercial practice.

7.3 Marking

Each container of tub ing shall be permanently and legibly marked with the size, quantity,

manufacturer's identification and batch number.
