BC31 polyurea semi-rigid plastic is a semi-rigid polyurethane material with stable performance and excellent mechanical properties of fatigue resistance and impact resistance.
BC31 is a star product of BC polyurea semi-rigid plastic series materials independently developed by Revo Plastic Technology. Relying on Revo's Digital Photonic Manufacturing Technology (DPM), BC31 can produce products comparable to the mechanical properties of traditional polypropylene (PP) materials, and is widely used in terminal products with high requirements for impact resistance.
Revo Plastic Technology passed a third-party independent testing agency, using the American National Standard ASTM D638, V type, 10mm / min as the test standard, to conduct a longitudinal tensile test on BC31, that is, a constant speed of 10mm / min along the longitudinal main axis of the BC31 sample Stretch until the specimen breaks to measure the load and elongation process of the BC31 specimen during this process.
The BC31 specimen breaks after a large strain occurs after yielding, which belongs to "ductile fracture", indicating that BC31 belongs to the category of ductile materials.
Comparing the tensile stress-strain curves of BC31 with traditional polypropylene (PP) materials, it can be clearly seen that BC31 has a similar "ductile fracture" yield curve.
The DPM technology of Revo Plastic Technology was matched with the BC31 polyurea semi-rigid plastic resin and the common technology on the market. The plastic resin was tested on the Instron 3366 universal tensile machine in accordance with ASTM D638 spline size and test standards And compare the test results horizontally.
Regardless of the comparison between a well-known domestic SLA technology supporting photosensitive resin, a well-known domestic sintering powder technology supporting resin powder, and an internationally renowned spray powder technology supporting resin powder, Revo Plastics Technology ’s DPM technology supporting BC31 polyurea semi-rigid plastic resin The tensile properties are far superior to the existing competitive materials in the market.
Repeated bending is not easy to break
BC31 has undergone professional tests on multiple impact properties, and its fracture resistance is particularly outstanding in practical applications.
Revo Plastic Technology passed a third-party independent testing agency to test the toughness of the BC31 non-notched specimen under the specified impact force using the American National Standard ASTM D4812 as the standard. The BC31 easily passed the test under the standard 23 ° C environment without breaking.
In the range of domestic additive manufacturing materials, BC31 is the first polyurea semi-rigid plastic material tested by ASTM D4812. With this advantage, the BC31 can be applied in large-scale applications where there is a high demand for bending resistance.
Both toughness and hardness
Based on excellent mechanical properties of fatigue resistance and impact resistance, BC31 also exhibits good hardness.
Revo Plastic Technology passed a third-party independent testing agency to test the hardness of BC31 with the American National Standard ASTMD2240 Shore Hardness Test Method as 79 Shore D.
BC31 Advantage Summary
