Sons' project on plastic.

[catchinit]

Someone please help him, he driving me crazy. Break tests were carryied out on 3 samples of ABS which have been thermoformed, (one was over heated, one perfectly heated and one too cool to form). The one which was heated to the correct time and formed perfectly had consistantly higher results in deflection at break and load at break. Can you explain what happens to the polymer chains when the plastic is - overheated/perfectly heated/too cool - to make this so?

Hm, I thought it was you who was doing a science degree. Note for the future, be careful what information you divulge on the net.

I am catchinit senior: jesus it's like the twilight zone in here! You watchin my house JustSia?

[JustSia]

lol nah I googled some info and strangely the previous question on polymers came up.

[catchinit]

Phew! Thought you the ex-wife there for a min lol. Will take your advice though. Many thanks...... now answer the darn question lol :-)

Wish I could, your best bet is to wait for science squad to log in. But I've been doing some googling and have found only very basic info. The last one I haven't had a chance to read yet, you can try and sign up for a free trial see if it will yield something useful, was here http://findarticles.com/p/articles/mi_hb3367/i s_200102/ai_n8099633

All I did was google 'thermoforming acrylonitrile butadien styrene' so you can just carry on with that. Good luck.
