What is Transparent PA and how does it differ from regular nylon?

Transparent PA is a specialized polyamide that combines the chemical resistance of semi-crystalline nylons with the optical clarity of amorphous plastics. Regular nylon is opaque. Transparent PA achieves ~92% light transmission while retaining terpene resistance and mechanical toughness.

Is Transparent PA safe for inhalation-adjacent applications?

Transparent PA holds ISO 10993 biocompatibility certification and USP Class VI classification. It is FDA-compliant for food contact, contains no BPA or phthalates, and produces no detectable micro-particle degradation when exposed to cannabis terpenes.

Can Transparent PA be used with all types of cannabis extracts?

Yes. Transparent PA is inert to distillate, live resin, rosin, and high-terpene formulations with no interaction, discoloration, or off-flavors across the full product spectrum.

How does Transparent PA compare to glass on clarity?

Both achieve approximately 92% light transmission. Transparent PA matches glass on optical clarity while adding drop resistance that glass cannot provide, and does not yellow over time.

Does switching from glass to Transparent PA require retooling?

Transparent PA is injection-moldable using standard equipment. The transition requires new molds but no new filling equipment — it integrates with existing cartridge filling processes.

Transparent PA Tanks for Cannabis Cartridges

Q: Why did PCTG (Tritan) fail in cannabis cartridges?

PCTG has a glass transition temperature of only ~80°C and cracked faster than polycarbonate when exposed to d-limonene under stress. Raw Garden scrapped 300,000 PCTG units after finding terpene-induced degradation that could shed plastic particles into the vapor.

Summary: Transparent PA (polyamide) is the optimal tank material for cannabis 510 cartridges because it combines 92% light transmission with complete terpene resistance, holds ISO 10993 and USP Class VI medical certifications, contains no BPA or leachable micro-particles, and survives drops that shatter glass — all while tolerating temperatures above 130°C without softening.

Why Tank Material Determines Cartridge Integrity

Cannabis terpenes like d-limonene are powerful organic solvents. They attack and crack older plastics from the inside out, starting at stress points around the 510 thread base. Glass eliminates the chemical problem but introduces fragility. Transparent PA delivers both chemical resistance and mechanical toughness.

Terpene-Proof Chemical Resistance

Transparent PA combines the chemical resistance of semi-crystalline nylons with the optical clarity of amorphous plastics. It is inert to distillate, live resin, rosin, and high-terpene formulations. In controlled testing, PCTG (Tritan) cracked faster than polycarbonate when exposed to d-limonene under stress. Raw Garden scrapped 300,000 PCTG units after discovering terpene-induced degradation.

92% Light Transmission

Glass-like clarity at ~92% light transmission, exceeding both polycarbonate (~88%) and PCTG (~90%). Does not yellow under UV exposure or heat aging.

Medical-Grade Safety Certifications

ISO 10993 biocompatibility certification and USP Class VI medical device classification. FDA-compliant for food contact. No BPA, no phthalates, no micro-particle degradation.
