General
Does KYDEX® sheet outgas when thermoformed?
At lower temperatures, residual processing lubricants may outgas. At temperatures above normal thermoforming temperatures (excess of 425ºF), PVC-based grades will begin to degrade and release HCl slowly. Please contact appLab™ for additional information and to obtain a copy of the product’s safety data sheet.
Does KYDEX® sheet support the growth of fungus and/or bacteria resistance (G21 and G22)?
KYDEX® sheet products are not a food source and will not support fungal nor bacterial growth when tested to ASTM G21/G22.
Miscellaneous Info
What is ECCN?
Export Control Classification Number SEKISUI KYDEX ECCN: NLR or “No License Required.”
What is the CAGE code for SEKISUI KYDEX?
CAGE Code (Commercial and Government Entity) is a 5-digit code that identifies companies doing business with the federal government. First and last digits are numeric. SEKISUI KYDEX CAGE Code: 0HZM3
What is the HS Tariff Code and does KYDEX® sheet meet this?
Are fires involving KYDEX® sheet more hazardous than a fire without KYDEX® sheet?
Fires involving KYDEX® sheet are no more toxic than any other fire.
The combination of fire gases released when KYDEX® sheet burns is similar to burning wood, fabric, and other materials commonly found in a building. The toxicity of building fire emissions from KYDEX® sheet is neither better nor worse than that of many other common materials. The amount of dioxins produced by the KYDEX® sheet in fires is found to be “insignificant.”
Are VCM emissions still a problem like they were in the 1970’s?
According to the EPA, the vinyl industry’s VCM emissions have been reduced by more than 99% since the 1970s.
There is no confirmed case on record where a member of the general population has been harmed by exposure to VCM.
The actual risk among five million individuals presumed to live within five miles of a vinyl production facility has been calculated to be less than 0.1 cases of cancer in the next 70 years.
For comparison, this is similar to the risk over a lifetime of smoking 1.4 cigarettes, drinking 0.5 liters of wine, and traveling 300 miles by car.
Can KYDEX® sheet or ALLEN® sheet be stored outside?
We do not recommend that KYDEX® sheet nor ALLEN® sheet be stored outside.
Can KYDEX® sheet or ALLEN® sheet products contain plasticizers?
No. KYDEX® sheet and ALLEN® sheet products are rigid thermoplastic sheet and will not contain plasticizing agents.
Does SEKISUI KYDEX recycle materials used in everyday manufacturing processes and daily tasks?
Yes. There are a number of ways in which we recycle our non-plastic materials from everyday use. Here are a few:
Metals, office paper, and corrugated cardboard are recycled.
Used oils are collected and converted into industrial fuel.
Wood pallets are recycled and turned into garden mulch.
Also, post-manufactured packaging is biodegradable and/or recycled. It is designed to minimize weight/volume to reduce fuel consumption and the amount of packaging received by customers.
How does KYDEX® reuse, renew, and improve?
Our Kaizen methodologies constantly seek to improve material yield and minimize waste. Our internal recycling process also re-extrudes out-of-specification product and reuses it as raw material.
How does KYDEX® save energy and conserve resources?
Air: The use of clean, non-smokestack energies, such as electricity, results in insignificant particulate matter or carbon dioxide emitted into the air.
Water: The use of water for processing is limited – water never comes in contact with the process; water is recycled internally, so no surface water is discharged
Energy: We save energy across the entire lifecycle of manufacturing.
Raw material is shipped in rail cars to minimize fuel consumption.
KYDEX® thermoplastic sheet requires lower processing temperatures compared to most other polymers.
High-efficiency motors and sophisticated temperature controls reduce energy consumption.
What is Type 2 PVC?
Type 2 PVC is high-impact PVC. Our PVC products would be considered Type 2 PVC.
What level of dioxins are really in KYDEX® products?
PVC is such a small source of dioxins that levels in the environment would be essentially unchanged even if vinyl were not being manufactured and used every day.
THE US EPA states that dioxin levels in the environment are declining while vinyl production is growing.
Studies by the US Vinyl Institute show trace, insignificant levels of dioxin in PVC resins and products.
The US Vinyl Institute confirmed the presence of low dioxin concentrations in wastewater samples from four US plants that manufacture EDC/VCM.
Which organizations do fair research on PVC and Vinyl and provide results?
Global Industry Alliance, Vinyl 2010, and Green Building Council of Australia.
Product Selection
Does SEKISUI KYDEX have products that meet IO 10993 (Biocompatibility) criteria?
Yes. KYDEX® T, KYDEX® 100, KYDEX® 430, and ALLEN® 8100BC meet ISO 10993-5 Cytotoxicity and ISO 10993-10 Irritation and Skin Sensitization criteria.
What is the mold shrinkage of KYDEX® sheet?
Mold shrinkage for male molds is 0.4% – 0.6% and female molds, 0.5% – 0.7%. See Technical Brief 140-B, Technical Brief 140-C and Technical Brief 140-E for details.
UV Protection
Are KYDEX® sheet products UV resistant for outdoor use?
No, most KYDEX® sheet products are not UV resistant. For outdoor applications, it is recommended that KYDEX® sheet be painted or have a UV protective spray (Clear Jet) applied to prevent the material from shifting color. KYDEX® 510 has a Korad film that provides the material with UV protection. There are a number of ALLEN® Thermoplastic sheet options for UV-resistant and weatherable applications. Please contact your Sales Representative or appLab™ for additional information.
