specific prescription and producing process. The film DX10A has excellent physical property, good heat resistance,
lower xylene extractable value, and better R22 freon resistance and R134a ageing resistance. Its physical
properties have been certified by Electric Material Quality Supervision and Testing center of Machinery Industry. It
is applicable for electrical insulation in the electrical motors of compressor in air-conditioner and refrigerator,
special electric motors and electric apparatus.
1. Technical requirements
1.1 Appearance: The film is supplied in rolls. Its surface should be flat and smooth, and should be free of
defects such as wrinkles, avulsions, particulate matter, blisters, pinholes and contaminations. Edges of rolls
should be tidy and clean.
1.2 Thickness and Tolerance:
Recommended nominal thickness as following:
75um, 100um, 125um, 150um, 188um, 200um, 250um, 300um, 350um
Thickness tolerance is +/-5%.
1.3 Normal Width: 1000mm. It could also be supplied in tapes.
Width of film ≤ 400mm tolerance is +/-0.1mm
Width of film>400mm tolerance is +/-1.0mm
2. Testing methods
2.1 Oligomer extraction value
Take a specimen film approx.12g, dry it for 60min+/-5min under the temperature of 160ºC+/-5ºC,
measure the weight (W0, precision is 0.1mg) after cooling. Then put 150cm3 analytical xylene into 500 cm3 flask, after
that put the specimen into the flask to do boiling xylene extracting operation for 24 hours. And then, clean the extracted
specimen with analytical xylene, and then dry it under the temperature of 160ºC for 8h. Finally, measure the weight of
the specimen (W1, precision is 0.1mg) after it cooled.
Calculate the extractable value of the tested specimen according to the following formula:
(W0- W1)¡W 0x100%= Extractable Weight (%)
2.2 Thermal shrinkage: As per Clauses 5.10 of Standard GB/T13950-1992.
Specimen treating conditions: Under temperature 150ºC+/-2ºC for
2.3 Other items shall accord with the stipulations in Chapter 5 of Standard GB/T13950-1992.
3. Inspection, marks, packing, transportation and storage
3.1 The product with the same operators, raw material, producing process, type and spec is defined as
3.2 Routine test shall include Clause 1.1, 1.2, 1.3, 1.4 and all items in Clause 1.5.
3.3 The product shall be packed with cartons or pallets. Special requirements on packing could be settled
upon negotiation. The product also could be supplied in tapes.
3.4 The storage life is 18 months at lower than 40ºC from the date of leaving factory. The product should be stored in
warehouse which is dry and clean as well as keep away from fire, heat and directly sunshine. If the storage duration
is more than 18 months, the product also could be used after being tested to be qualified.
