#1 & #2 digits
Identifies the base polymer.
See the end of this document for a complete list of RTP Series.
Resin systems are numbered sequentially 01 through 47, with 01 representing polypropylene, 02 nylon, 03 polycarbonate, etc.
The leading zero on Series 01 through 09 is often dropped for simplicity.
Resin systems that have an alphabetical character immediately following the fourth digit use an alternate base polymer (ie: 200A signifies nylon 6, 200B nylon 6/10, 200C nylon 11, etc.).
#3 digit
Identifies the primary additive/filler.
- 0 — Glass Fiber
- 1 — Glass Fiber
- 2 — Talc
- 2 — Glass Fiber/Glass Bead Blend
- 3 — Talc or Mineral
- 3 — Glass Fiber/Stainless Steel Blend
- 4 — Calcium Carbonate or Mica
- 5 — Flame Retardant
- 6 — Stainless Steel Fiber
- 7 — Glass Fiber/Mineral Blends
- 8 — Carbon Fiber
- 9 — Carbon Fiber
#4 digit
Identifies the loading level of the primary additive/filler.
For glass fiber (third digit of 0 or 1) and carbon fiber (third digit of 8 or 9) reinforced compounds the following percentage scale is used with regard to loading levels. (# x 5 + 5 = %)
- 0 — Neat/Base
- 1 — 10%
- 2 — 15%
- 3 — 20%
- 4 — 25%
- 5 — 30%
- 6 — 35%
- 7 — 40%
- 8 — 45%
- 9 — 50%
- 10 — 55%
- 11 — 60%
- 12 — 65%
- 13 — 70%
- 14 — 75%
Decimals between 0.1 and 0.9 are used for loading levels of less than 10%.
Other primary additives/fillers identified by the third digit may use different scales to indicate their loading level.
Suffix
Used for grade designations or for identifying secondary additives/fillers.
- AR — Aramid Fiber (%)
- CC — Chemically Coupled
- CF — Carbon Fiber (%) — Only used when combined with glass fiber
- EM — Easy Mold
- EG — Extrusion Grade
- F — Foamed
- FR — Flame Retardant
- FR A — Updated FR Formulation
- FR NH — Halogen-Free FR System
- GB — Glass Bead (%)
- HB — UL HB Flammability Rating
- HEC — Highly Electrically Conductive Fiber (%) — Nickel-coated carbon fiber
- HF — High Flow
- HI — High Impact
- HM — High Modulus
- HS — Heat Stabilized
- L — Lubricated
- LE — Low Extractable
- LF — Low Flow
- LP — Low Plate Out
- M — Mineral (%)
- MF — Medium Flow
- MG — Milled Glass (%)
- MS — Molybdenum Disulfide (%)
- NS — No Substitutes
- SE — Self Extinguishing
- SI — Silicone (%)
- SP — Small Pellet
- SPR — Surface Protection product – Only used with standard nomenclature
- TC-I-XX — Thermally Conductive compound, electrically insulating, with the XX specifying the relative through-plane thermal conductivity
- TC-C-XX — Thermally Conductive compound, electrically conductive, with the XX specifying the relative through-plane thermal conductivity
- TFE — PTFE (%)
- UV — Ultraviolet Stabilized
- Z — FDA Compliant Ingredients
When any of the above suffixes marked with a “(%)” have a number following them, this number identifies the loading of this additive.
X Series products
RTP Company materials that follow the numbering convention #1 #2 99 X # # # # # are our custom and/or proprietary-formulated compounds. The five or six digits after the “99 X” denote an engineering notebook page number and do not identify additives/fillers or loading levels.
Color numbers
- Natural — No pigments added
- Black — Standard amount of black pigment or material is inherently black
- Nat/Blk — Carbon fiber product (or other dark filler) with no pigment
- Blk/Blk — More than the standard amount of black pigment or carbon fiber product with standard amount of black pigment
- S-##### — Standard color
- SL-##### — Laser-markable
- SS-##### — Straight shot color
- SSL-##### — Straight shot laser-markable
- Z-##### — FDA Compliant Ingredients color
- ZL-##### — FDA Compliant Ingredients laser-markable
The numeric digits of a color number are assigned in sequential order as a unique identifier and are not part of any scale to indicate color hue.
