Our wide-ranging analytical testing capabilities can be used to characterize your resins in numerous ways to determine physical, mechanical, and chemical attributes. Examples of our analytical testing measurement capabilities include:

• Acetaldehyde content and generation rates
• Carboxyl end group (CEG) analysis
• Color and haze
• Density, melting and crystallization behavior
• Intrinsic viscosity
• Melt flow curves
• Natural stretch ratio (areal planar strain) using PTI's Freeblow Device
• Tensile and yield modulus

When made into bottles, additional testing can include vertical load, burst strength, creep, drop impact, environmental stress cracking, coefficient of friction, O2 and CO2 permeation testing.
