Inoplast PL

Inoplast PL is a single-faced adhesive tape of polyester(PET) non-woven fabric backing which is coated by excellent waterproof butyl rubber pressure-sensitive adhesive (PSA).
Usable for various applications which require damp proof and durability since it shows well-balanced and high adhesion in a wide range of temperature and the PSA is superior in air-tightness.
1. Structure
- Polyester non-woven fabric
- Butyl rubber PSA
- Release paper liner
2. Application
- Temporary fixing of exterior wall material, and waterproof packing of joints
- Waterproof sealing around interior plumbing
- Waterproof sealing of waterproofing sheet joint, skirt, or drain at rooftop
- Joint sealing of roofing membrane
- Waterproofing around window frame for residential house
3. Temperature dependency of adhesion
- Test plate： Stainless plate
- Test method： Application of specimen at conditions of 23°C and
RH. Keep the specimen at each
- Temperature for 20mins. Specimen to be peeled off at each temperature by 180°peeling.
4. Variation per time (Cycle test)
- Test plate：Stainless plate
- Test method：Tape to be applied at 23°C,
- RH. Condition 1： Thermostatic chamber at 80°C Condition 2： Water tank at 20°C
- Specimen to be placed in condition 1 and 2 everyday (Cycle). After certain elapsed days, specimen to be kept under the circumstance of 23°C, RH for 2hrs. Then adhesion to be measured by 180°peeling.
- Remarks: No change in appearance (such as cracking, etc.) in this test
- Adhesion of Inoplast PL increases as times elapse. Furthermore, no decline of adhesion even under water or rapid change of temperature.
5. Heat resistance property
Test method： Specimen to be applied to glass plate vertically. Visual observation of appearance of specimen, which is placed in each temperature condition inside thermostatic chamber (50, 75, 100°C, and 120°C) after certain days. Inspection items: Adhesive flow, generation of crack, and shrinkage of tape
6. Cold resistance property
- Judgment criterion
A：Nothing peculiar
B：Slight declination of flexibility, but no peel off
C：No flexibility and break off of tape, but no peel off D：No flexibility and break off of tape, and tape peel off
- Test method： In accordance with Fed. Method Std. №101B Method 2051
- Specimen to be applied to polyethylene film or Kent paper at normal temperature. Keep it under 65°C for 24hrs. Then keep it under each low temperature for 2hrs or more. Then roll it on iron bar which was also chilled under the same condition as specimen. Observe specimen’s appearance. (Operation was also done in the same cooling conditions) Inoplast PL performs its adhesion good enough under low temperatures.
7. Weather resistance
- Test method： Weather-O-Meter conditions: 18mins of rain in 120mins cycle
25mm width specimen to be applied to stainless plate at room temperature. Appearance, tensile strength, and elongation of specimen were measured after exposed to sunshine
carbon weather-o-meter (WE,SUN-HC).
- No declination of adhesion of Inoplast PL even after long term outside use. Furthermore, its adhesion even tends to increase in such condition. Moreover, no cracking, nor shrinking were found.
8. Precautions for use
- Please apply tape after removing dirt, dust, moisture and oil from the surface since enough adhesion is not obtainable if the surface is stained.
- Please press firmly after applying the tape to obtain enough adhesion.
- For the keeping of tape, please avoid direct sun-ray and the heat sources as heating equipment and store it at cool place.
- Please do not use for electrical insulation purpose other than electrical insulation tape.
- Please do not apply directly to the car body, furniture, walls, glass and PVC products since causing of discolor, adhesive residue, and paint peel-off.
- Since adhesive residue and rash may be caused by using of other tapes than adhesive tape for skin, please do not apply the tape to the skin directly.
- Please test well before actual use as tape may contaminate or leave adhesive depending on type of adherend.
- Please consult us for special application.
- Described values are examples of measured values, and not guaranteed
values.
- The lead-time varies by conditions. Please inquire us for obtaining updated information.
- Specification may be subject to change without prior notice.
- Please verify whether the tape is suitable for your application before use.
- We cannot be held responsible for any damage incurred as a results of using. Please use after enough confirmation.
