Divided into eight categories, as detailed in the table: Logo abbreviations< /strong> Polymer name Common products Heat-resistant temperature PETE/ PET Polyethylene terephthalate (PET, Polyethylene terephthalate) PET bottles, commercial beverage bottles, Edible oil bottle…wait 60 ~ 85 degrees HDPE/ PEHD high density polyethylene (PE, High-density polyethylene) shopping bags, recycling bins, Cup holder, fresh milk bottle, Alcohol bottles, sports field equipment Composite plastic wood…etc. 90 ~ 110 degrees PVC/ V Polyvinyl chloride (PVC, Polyvinyl chloride) Non-food bottles, plastic wrap, Egg carton, seasoning tin… etc. 60 ~ 80 degrees LDPE/ PELD Low Density Polyethylene (PE, Low-density polyethylene) Plastic bag, medicine bottle, Various molded laboratory equipment…etc. 70 ~ 90 degrees PP Polypropylene (PP, Polypropylene) Auto parts, food containers, Food utensils, soy milk bottles, alcohol bottles, Physiological salt bottle.…etc. 100 ~ 140 degrees PS Polystyrene (PS, Polystyrene) Self-service trays, toys, Yakult bottles, Ice cream box, instant noodle bowl, Styrofoam… etc. 70 ~ 90 degrees Others Polycarbonate (PC), Polylactic acid (PLA), Polymethyl methacrylate (PMMA, acrylic), Melamine resin Food and tableware Polycarbonate (PC) heat resistant 120 ~ 130 °C; Polylactic acid (PLA) heat-resistant 50 °C; Acrylic (PMMA) heat resistance 70 ~ 90 °C; Melamine resin heat resistance 110 ~ 130 °C ABS ABS resin (ABS) Food and tableware 70 ~ 100 degrees

Question 2

What's EN45545-2 R22/R3?

Accepted Answer

What is EN45545-2 R22/R23? EN45545-2 (R22/R23) is the requirement for the burning behavior of rail vehicles in the European fire safety standards.  For our silicone sealing strips, we have added a series that meets the most stringent "HL (Hazard Level)-3" series.  It is a product with extremely excellent flame retardancy and low smoke generation, and has been confirmed to meet the ISO/IEC 17025 accredited testing laboratory, so it can be used as a gasket or sealing material for railway vehicles.  The design is embedded with "stainless steel (SUS443) stamped metal", which has excellent rust resistance, flexibility and safety, and is used in various use environments such as harsh outdoor places.  It can be manufactured as a single product, not necessarily as a silicone trimming strip, such as: gaskets and sealing materials for railway vehicles, testing equipment, electrical equipment, packaging materials for testing equipment, cable sleeves, etc.

Question 3

What is Sube up? Why to choose it?

Accepted Answer

What is Sube up? "Sube up" is a technology in which a film layer made of a special smooth hard resin is coated on the surface layers of TPO (olefin elastomer) and TPS (styrene elastomer) by simultaneous extrusion molding. Generally, TPO , TPS, etc. are materials that disperse fine rubber powder in resin or have a block structure, so the surface of the extruded product has rubber elasticity and is extremely non-slip. Static electricity is generated due to poor fluidity, adhesion to mating parts and non-polar materials. In addition, "Sube up" is a processing technology in which a smooth layer made of a special smooth hard resin is formed with a film (about 20μm ), so it will not damage the flexibility of the substrate, so it should be widely used as Sealing materials and gaskets.   Why choose Sube up? 1. Excellent sliding characteristics 2. Excellent stain resistance 3. Excellent durability 4. Excellent anti-sticking performance 5. Excellent chemical resistance

Question 4

Is ScienceRich commissioned to print out by 3D printing?

Accepted Answer

1. Can we print with POM material? A: It used to be printed on POM material, but it wasn't of good quality. So it isn't allowed this time.   2. Is there MOQ limited?  By weight or quantity? A: No MOQ limited, but technical cooperation with Japan company, print in Japan.  We'll suggest MOQ according to the quantity, size and printing time.  The quotation is based on printing time.   3. What is the criteria for tolerance? A: There are no specific tolerances because it is based on the material, size, shape...etc.  but It can be as the targeted by intermediate tolerances of JIS0405-B.   4. What is the delivery schedule? A: About 3~4 weeks, as the answer of question 2, depending on the printing time.   5. Does the PEEK material contain Glass fiber (GF),Carbon Fiber (CF)? A: PEEK materials can be selected for GF/CF or non-GF/CF.   6. Can the surface be glossy or texture? A: After printing, it can be proceesing as glossy.   7. What is the temperature resistance of 3D printing PEEK material? A: The temperature of PEEK material is 220～260 degrees.
