NOTICE  TO  USERS:  Values shown  are  based on testing of  laboratory test specimens and represent  data  that   fall within the  standard  range of properties for natural material. These values  alone do not  represent  a sufficient basis  for any part  design  and are  not  intended  for use in establishing maximum, minimum,  or  ranges of  values  for specification purposes.  Colorants  or  other  additives may  cause significant  variations in data  values.
Properties of  molded parts  can be influenced by a wide variety of  factors including, but  not  limited to,  material selection, additives, part design,  processing  conditions and environmental  exposure.  Any determination of  the  suitability of  a particular  material and part  design  for any use contemplated by the  users and the  manner  of  such use is the  sole  responsibility of  the  users,  who  must assure themselves that   the  material as subsequently  processed meets the  needs of  their particular product  or  use.
To the  best  of  our  knowledge, the  information contained  in this  publication is  accurate; however, we  do not  assume  any liability whatsoever for the  accuracy and completeness of  such information. The information contained  in this publication should  not  be construed  as a promise or guarantee of  specific properties of  our  products. It is the  sole  responsibility of  the  users to  investigate whether any existing patents  are infringed by the  use of  the  materials mentioned in this publication.
Moreover, there  is a need to  reduce human  exposure to  many  materials to  the  lowest  practical limits in view of  possible  adverse effects. To the extent  that   any hazards may  have been mentioned in this publication, we  neither suggest nor  guarantee that   such hazards are  the  only  ones
which exist. We recommend   that   persons intending to  rely on any recommendation or  to  use any equipment, processing  technique, or  material mentioned in this publication should  satisfy themselves that   they  can meet all applicable safety  and health  standards.
We  strongly recommend  that   users seek and adhere to  the  manufacturer’s  current instructions for handling  each material they  use,  and to
entrust the  handling  of  such material to  adequately  trained personnel  only. Please call the  telephone  numbers  listed for additional technical information. Call  Customer Services  for the  appropriate Materials Safety  Data Sheets (MSDS)  before  attempting  to  process our  products.
