How is this weather resistant?
We tested the impact of accelerated weathering on the following mechanical properties:- Tensile Strength- Young's Modulus- Charpy Impact StrengthAccelerated Weathering settings:The fluorescent UV light exposure follows the standard ISO 4892.3
The type of UV light is UVA-340.
The irradiance is 0.76W/m2 at 340 nm.
The cycle is 102 min for UV only and 18 min for water spray.
The black panel temperature is 63± 3 °C
The total test time is 60days (720 cycles) equivalent to ~3+ years*
*3rd Party Testing By: Micom Laboratories
[Rule of thumb: acceleration factor was found to be: 21.5]
Is this food safe?
There is no certification for food safety with the FDA, but this material does have certifications for Europe.
Regulation (EC) No 1935/2004 of the European Parliament and of the Council of 27 October 2004 - Sensorial examination odour and taste test: PASS
Test Method: With reference to DIN 10955: 2004
(EU) No 10/2011 and its amendment (EU) 2020/1245 Regulation - Specific migration of heavy metal: PASS
Test Method: With reference to EN13130-1:2004, analysis was performed by ICP-OES and ICP-MS.
How is this chemically resistant?
Reference standard: ISO 175:2010
Methods of test for the determination of the effects of immersion in liquid chemicals
- Immersion temperature: 23±2˚C
- Immersion period: 7 days
- Test the mechanical properties before and after immersion
- Resistance to the chemical: The mechanical properties* must maintain over 70% after 7 days immersion
*Tensile Strength, Young's Modulus and Charpy Impact Strength
Tested Liquid Chemicals:
- Water (pH=7) -> Result: RESISTANT
- Household cleaners (stain remover) (pH=11) -> Result: RESISTANT
- Household cleaners (sterilizer) (pH=4) -> Result: RESISTANT
- Vinegar food grade (pH=4) -> Result: RESISTANT
- Vinegar concentrate (pH=4) -> Result: RESISTANT
- 75% alcohol (pH=6) -> Result: RESISTANT
- Fertilizer nutrient solution (pH=6) -> Result: RESISTANT
Do you sell refills?
We are sorry but we do not sell refills at this time
Is this material recyclable?
Unfortunately there is no great answer for recycling PLA at this time. Our cardboard spools are biodegradable but there is no great way to recycle PLA at this time.
