Senrui Precision - Plastic Material Database · Nine-Dimension Performance Map · Key Physical Property Comparison
Nine-Dimensional Radar Chart Analysis
Based on statistics of the classification field (cat) of the material database on this page, it visually presents the coverage breadth and structural proportion of Senrui's plastic material library.
This page focuses on the plastic resin family; elastomers (TPU / TPE) and metal powders (MIM feedstock) are placed in the dedicated "3D Printing Materials" and "MIM Materials" libraries respectively, where further selection can be done on the corresponding pages if needed.
Locate the optimal material in three steps: first select the industry scenario, then set performance priorities, and the system instantly recommends matching grades from this database (click a recommendation card to view the nine-dimensional map).
Which industry scenario is your part mainly used in? This determines basic requirements for temperature resistance, strength, and regulatory certification.
In this scenario, which property matters most? The system will rank candidate materials accordingly.
Complete the first two steps to get recommended results.
Address high-frequency confusion in engineering selection with hands-on advice based on physical-property data.
If a part’s continuous operating temperature is >100℃, commodity plastics (e.g., ABS, PP) will experience thermal deformation or even softening. It is recommended to prioritize engineering plastics with a heat-resistance rating ≥8 (PA66, PC, heat deflection temperature approx. 120–140℃) or specialty engineering plastics (PEEK can withstand 260℃ long-term, PPS approx. 220℃). When selecting, be sure to check the ‘Heat Deflection Temperature (HDT)’ rather than the melting point, and confirm whether it must bear load at high temperature.
Flame retardancy requirements usually map to UL94 ratings. Materials in this library with a flame retardancy score of ≥7 are better suited to flame-retardant applications: PC/ABS alloys, PPS and PEEK reach V-0 relatively easily, while ABS, PP and similar materials require flame-retardant modification to reach V-0, at the cost of some impact strength and flowability. When selecting materials, confirm with the engineer whether a flame-retardant modified grade is used and its specific rating.
For transparent parts, prefer PC or PMMA: PC has high transparency and impact resistance (bulletproof grade), suited to transparent parts that must bear load (lampshades, goggles); PMMA offers better light transmittance and surface hardness but is more brittle, suited to appearance parts. ABS is inherently opaque and cannot achieve high transparency through dyeing, so it should be avoided in transparent applications.
Food-contact parts must use grades certified for food contact (e.g., FDA, EU 10/2011). PP is a typical food-grade plastic (chemically resistant, microwave safe), and HDPE is also commonly used; mixing with recycled material should be avoided, and attention should be paid to whether high-temperature retorting is required—when retorting is needed, choose PP instead of PS. Applications labeled with the "Food" tag in this library correspond to such scenarios.
Engineering plastics (PA, PC, POM) typically cost 2–4 times as much as commodity plastics, but they can replace metal, reduce weight and eliminate secondary operations; specialty engineering plastics (PEEK, PPS, LCP) can reach 5–10 times the price of engineering plastics and are cost-effective only in demanding applications such as high temperature, severe corrosion or high dimensional stability. The recommended approach is to select by the lower limit of required performance first, then choose the most cost-effective grade among those that meet the requirements.
Grades marked 'Senrui Internal Material' are Senrui's existing inventory; the data has been checked against the manufacturer's TDS and typical industry reference values and can be used directly for quotations and prototyping; 'Reference Generic Material' is a general material knowledge base for lateral comparison and scheme pre-study, with the actually purchased grade subject to Senrui's confirmed inventory or designated manufacturer.
From grade recommendation and property verification to prototyping and mold trials, Senrui's material engineers can give actionable material-selection and molding advice based on your operating conditions. You can also go straight into the dedicated material library for deeper selection.
