What material is the pe foam double-sided adhesive made of?
PE foam double-sided tape is based on polymer foam material, coated with high-performance pressure-sensitive adhesive (acrylic adhesive or rubber-type adhesive) on both sides, and compounded with single-silicon or double-silicon release material. Available in a variety of thicknesses, densities, and colors, and can be rolled or die-cut to various shapes, foam tape has excellent weather resistance, chemical resistance, cushioning, sound absorption, and superior adhesion, suitable for Signage, decoration, building materials, home accessories, electronic appliances, automotive interiors, medical protection, precision machinery and other industries.
PE foam double-sided tape refers to a double-sided tape made of acrylic glue on both sides of the PE foamed substrate. The main colors are black and gray. It is suitable for sticking and fixing of photo frame decorative strips, furniture decorative strips, car decorative strips, wave boards, wheel arcs, baffles, plate brake lights, car logos, motorcycle signs, electrical nameplates, tops, etc. Features: strong adhesion, good retention, UV resistance, temperature resistance, water resistance, solvent resistance and plasticity resistance. Applicable temperature: -20℃~120℃.
testing method:
•Working principle: Hang the test plate with the sample on the test stand vertically, and hang the weight of the specified weight at the lower end, and measure the displacement of the sample after a certain period of time or the time required for the sample to be completely detached. The ability of the adhesive tape to resist pull-off.
•Instrument structure: It is mainly composed of timing mechanism, test board, loading board, weight, frame and standard pressing roller.
•Technical indicators: Weight—1000±10g (including the weight of the loading plate)
Test board—60(L)*40(B)*1.5(D)mm (same as loading board)
Roller load: 2000±50g Rubber hardness: 80°±5° (Shore hardness)
Timer - 99 hours 59 minutes 60 seconds Station - 6 stations
Net weight—12.5kg Power supply—220V 50Hz
Dimensions—600(L)*240(B)*400(H)mm
Operation method:
•Place the instrument horizontally, turn on the power switch, and place the weight in the slot under the hanger.
• The unused station can be stopped by pressing the "Close" button, and the "On/Clear" button can be pressed to re-time.
• After removing the outermost 3-5 circles of adhesive tape from the adhesive tape test roll, unwind the test roll at a rate of about 300 mm/min (the separation layer is also peeled off at the same rate for sheet-like samples). At intervals of about 200 mm, cut a sample with a width of 25 mm and a length of about 100 mm from the middle of the adhesive tape. Unless otherwise specified, the number of samples in each group shall not be less than three.
• Scrub the test and loading plates with a cleaning agent, then dry them carefully with a clean gauze, and repeat three times. above, until the working surface of the board is clean by visual inspection. After cleaning, do not touch the working surface of the board with hands or other objects.
• Under the conditions of temperature of 23℃±2℃ and relative humidity of 65%±5%, according to the dimensions specified in Figure 2, stick the sample parallel to the longitudinal direction of the plate to the middle of the adjacent test plate and the loading plate. Roll on the sample with a pressure roller at a speed of about 300 mm/min. Note that when rolling, only the force generated by the mass of the pressing roller can be applied to the sample. The number of rolling can be specified according to the specific product conditions, if there is no specified, then rolling back and forth three times.
• After the sample is pasted on the board, it should be placed for 20 minutes at a temperature of 23°C±2°C and a relative humidity of 65%±5%. Then will test. The plate is held vertically on the test stand, and the loading plate and weights are lightly pinned. The entire test stand is placed in a test chamber that has been adjusted to the required test environment. Record the test start time.
• After the specified time, remove heavy objects. Use a graduated magnifying glass to measure the sliding displacement of the sample, accurate to 0.1mm; or record the time when the sample falls off the test plate. If the time is greater than or equal to 1h, the unit is min, and the unit is s if it is less than 1h.
Processing of test results:
The test result is the arithmetic mean of the displacement or the fall-off time of a group of specimens.
Application areas:
•Electronic market: mobile phones, computers, digital cameras, mechanical panels, membrane switches, etc.;
•Automobile market: decorative strips, auto parts, car logos, car perfumes, etc.;
• Aerospace;
•Household market: hooks, furniture, toys, handicrafts, etc.
