POE is composed of octene and polyolefin resin, and the continuous phase and the dispersed phase exhibit a two-phase separated polymer blend.
POE features:
(1) The soft chain of octene is crimped and the crystallized ethylene chain acts as a physical crosslinking point, so that it has both excellent toughness and good processability.
(2) There is no unsaturated bond in the molecular structure of POE, and it has excellent aging resistance.
(3) POE has a narrow molecular weight distribution, good fluidity, and good compatibility with polyolefins.
(4) Good fluidity can improve the dispersion effect of the filler and also increase the weld line strength of the product.
Basic characteristics of POE:
(1) POE has the general physical properties of a thermoplastic elastomer such as moldability, waste recycling, and vulcanizate properties.
(2) The price is low, and the relative density is small, so the volume and the price are low.
(3) Excellent heat resistance and cold resistance, and a wide range of use.
(4) Good weather resistance and aging resistance.
(5) Oil resistance, compression set resistance and wear resistance are not very good. Scope of application: mainly used for modifying and toughening PP, PE and PA to make bumpers, steering wheels, pads and so on in the automotive industry. The wire and cable industry requires high insulation and jacketing for heat resistance and tolerability. Also used in industrial products such as hoses, conveyor belts and molded products. Medical equipment, household appliances, stationery, toys, etc., as well as packaging films.
EVA:
EVA is widely used in foam shoes, functional shed film, packaging molds, hot melt adhesives, wire and cable and toys.
Features of EVA and PEVA:
(1) Biodegradable: It will not cause harm to the environment when discarded or burned.
(2) Similar to the price of PVC: EVA is more expensive than toxic PVC, but PVC is relatively cheaper than phthalate.
(3) Lighter weight: EVA has a density ranging from 0.91 to 0.93, while PVC has a density of 1.32.
(4) No odor: EVA does not contain organic odors like ammonia or other.
(5) Free of heavy metals: in accordance with the relevant international toy regulations (EN-71Part3 and ASTM-F963).
(6) Phthalate-free: suitable for children's toys and does not pose a plasticizer release risk.
(7) High transparency, softness and toughness: the application range is very broad.
(8) Super low temperature resistance (-70 ° C): suitable for icing environment.
(9) Water, salt and other substances: stable in most applications.
(10) High heat sticking: It can be firmly attached to nylon, polyester, canvas and other fabrics.
(11) Low bonding temperature: can speed up production.
(12) Screen printing and offset printing: products that can be used for multiple patterns (but EVA type inks are required).
EVA features:
EVA resin is characterized by good softness and rubber-like elasticity. It can still have good flexibility, transparency and surface gloss at -50 °C, good chemical stability, aging and ozone resistance. Good, non-toxic. It has good blending property with filler, and has good coloring and molding processability.
EVA use:
EVA resin is widely used. In general, EVA with a vinyl acetate content of less than 5% is mainly used for film, wire and cable, LDPE modifier, adhesive, etc.; EVA products with a vinyl acetate content of 5%-10% are Elastomeric film, etc.; EVA with vinyl acetate content of 20%-28%, mainly used for hot melt adhesives and coated products; vinyl acetate content of 5%-45%, the main products are film (including household film) and film Materials, injection molding, molded products, foamed products, hot melt adhesives, etc.
POE and EVA:
POE and EVA have a certain mutual substitution in the toughening effect, and are widely used in the general toughening of PP and PE. The manufacturer mainly considers the cost factor to choose. In the toughening effect of PP, the general POE is slightly better than EVA. Some different characteristics of POE and EVA are suitable for other special performance requirements except for toughening. In film applications, EVA has better barrier properties, while POE generally does not. EVA can improve the printing and dyeing effect of PP, but it will reduce the aging resistance, while POE has good aging resistance and excellent heat resistance and cold resistance.

Important Caution:
1． Before use the glue gun, check if the plug cord into electrical outlet properly;
2． When glue gun in first use, the heating element will have small smoke, it is normal situation, but the smoke will disappeared after 10 minutes;
3． After power, not for a long time in standby mode(not longer for 20 minutes), when the suspension of use, unplug first.
4． Avoid to use the glue gun under very hot or very cold environments.
5． Better not work under direct cold wind blowing, it will reduce efficiency and loss power
6． When in continuous using, do not press the trigger with great pressure, and try to squeeze out the un-melted glue, it would damage the glue gun
7． Not applicable for bonding heavy objects or objects needed strong adhesive
8． The quality of glue stick will directly influence the glue gun function and sticking objects quality;
9． If the power cord is damaged, do not replace it by yourself, must ask for professionals to replace it.
10． This tools must b e placed in its position when not in use. And storage before the tools complete cooled.
11． Be careful when using any other electrical appliance with flammable material.
12． Not applicable for a long time in the same place.
13． Do not use an explosive gas atmospheres.
14． Note that heat may be the line of sigh, combustible materials.
15． Do not leave equipment unattended when switched on.
16． This appliance is not intended for use by persons(including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Using methods
1. Glue gun using voltage is 110-220V AC,50/60Hz;
2. Tip gun forward on stand and place a piece of cardboard under the nozzle
3. Use 7-8mm (mini trigger glue gun), 11-12(big trigger glue gun), insert glue sticks through
tunnel at back of gun
4. After power, wait for 5-10 minutes to allow glue to soften
After glue softens, squeeze trigger to feed glue through glue barrel. Excessive force will damage glue gun. Put down nozzle after work, disconnect the power plug
