As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade.Please review our full return and shipping policy here.
Measure Twice, Cut Once
Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring Tape
Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End Hook
The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).
Sanitizing Acrylic and Polycarbonate Sheet [X]
Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.
Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.
Clear polycarbonate sheets, known by the trademarked names Lexan, Makrolon, Makroclear and others, are a particular group of thermoplastic polymers. Polycarbonate is a very durable material. Although it has high impact-resistance, it has low scratch-resistance, so a hard coating can be applied for added protection. Polycarbonate characteristics are quite like those of polymethyl methacrylate (PMMA, ACRYLIC), but polycarbonate is stronger and usable in a wider temperature range.
Polycarbonate is a versatile, tough plastic used for a variety of applications, from bulletproof windows to compact disks (CDs).
It comes in transparent and opaque varieties. The main advantage of polycarbonate over other types of plastic is unbeatable strength combined with light weight. Polycarbonate is much lighter than glass, and is nearly unbreakable. Bullet-resistant variations are available and are used in windows and enclosures usually seen inside banks are often made of polycarbonate.
How to Clean Polycarbonate Sheet
General Cleaning 1. Rinse surface with warm water to loosen preexisting dust, dirt and grime. 2. Gently wash surface with a mild soap and a soft microfiber cloth or sponge. 3. Rinse thoroughly with lukewarm water. Dry completely with a soft, dry cloth.
Removing Oil and Tar 1. Rinse with warm water to loosen preexisting dust, dirt and grime. 2. Gently rub surface with a 50/50 isopropyl alcohol and water mixture using a soft, non-abrasive cloth. 3. Immediately rinse material with water and dry using a soft, dry cloth.
Removing Heavy Markings (e.g. graffiti, paint, marker, inks, glazing components) 1. Rinse with warm water to loosen preexisting dust, dirt and grime. 2. Gently rub surface with Naphtha VM&P grade, isopropyl Alcohol, or butyl cellosolve, using a soft, non-abrasive cloth.
Removing Adhesive-Backed Labels 1. Stubborn adhesives can be removed using isopropyl alcohol, Naphtha VM&P grade or kerosene.
Removing Scratches 1. Deep scratches and gouges made by sharp objects such as keys, screwdrivers and knives cannot be repaired. 2. Fine scratches can be cosmetically hidden by using our Novus 2, followed by a polishing agent such as Novus 1.
Special Note: Always rinse edges of polycarbonate with generous amounts of warm water, as the edges of polycarbonate sheet are not protected with an abrasion and chemical resistance hard coating.

I am slow in reply, however, I wanted to thank your team for the excellent work in the attached order. The cuts were perfect so the plastic sheets perfectly replaced the broken green house glass. I had planned to glue the two sheets where they met to air drafts out, however, the cuts were so precises that I just set the one sheet on top of the other.

I had a large glass piece in my greenhouse blow-out in a windstorm and had trouble finding a replacement glass supplier in my rural area. Ordered two pieces of 0.220 so it could ship UPS and am super pleased with results. Cuts were so precise the I just set the two pieces over each other with no glue and they fit and look great - as clear as the glass. And if this blows out in a windstorm it will not break!

$127.00 for 8 sf of .177 clear polycarbonate. Are you kidding me? Am I missing something?

Thanks for the volume discount! Great to work with you!

I think I overpaid because there are cheaper versions of polycarbonate if you dont need the "machine grade" features

Hi mr/miss,
I would like to know if you could make a 20mm thickness polycarbonate sheet.
2014-09-26
Easy to work with, both the material and interstate plastics!

Our order got here earlier than the date promised. Not a bit of damage and for a great price so I definitely will order from Interstate Plastics again in the future.

I ordered 400 sheets of cut polycarbonate on June 25 and received the order yesterday. Your prices are excellent and this was the 2nd time ordering from IP. 1 week from placing order to receiving order. Excellent work.

That's just a great product, and Interstate Plastics' customer service is extremely helpful and knowledgeable. Don't waste your time with TAP.

Everything arrived damage free, quality of the polycarb is good - I think the shipping is expensive for large orders but I don't know if that's just UPS, it seems a bit steep. I have used them before and I will continue to use them as I do trust them.

I havent left a review before but I wanted to share my improved experience. First of all, this latest shipment of polycarbonate was perfect and arrived a day early. My first experience ever with Interstate was not a good one. The customer service agent I spoke with was unprofessional and didnt seem all that knowledgeable. I told myself I wouldnt go back to insterstate so as to spare myself from dealing with this person. A few months later, I was left with interstate as the best priced option I could locate for polycarbonate sheet. I priced the order online and then called it in. THIS TIME I was absolutely taken care of. They answered all of my questions with specific helpful answers. I was treated like an actual HUMAN BEING. The best part was, I explained my frustration with the individual I had dealt with before and was told they were no longer with interstate. I guess they noticed what was going on, and I feel a lot better ordering from them in the future. Thanks for all your help!

Outstanding service and product. 5 stars.

Interstate is a reliable supplier. Cant recall ever having an issue and cant beat the price.

Buying online has proven to be the best route for us. We purchase monthly, and it's nice to get a low price without all the sales talk. No complaints here.
